Scientific method: Scenario 1
Scenario assigned by instructor: _ an unexpected road block/detour while driving to work, school, etc
Often, application of scientific methods gives persons an opportunity to conclude about causes of their problems in an expedient manner. However, to successfully solve a problem, an individual has to start by identifying the problem at hand which is then followed by evaluation of solutions using scientific methods. A scientific method works best when an in this scenario begins by asking myself why is there an unexpected roadblock on this route? Then the next step would be trying to find out if there are other roots leading to my workplace and to identify if there are roadblocks. However, it is also prudent to

I walk up to the front door and switch my lights on. However on walking up to where my I always keep my stereo system to switch it on there is no music not even a sound to show that it is working regardless of how many times I try to switch it on.
The first question that will definitely come into my mind will be “why is it no working?” the curiosity of wanting to find out why my stereo is not working would definitely lead me to start evaluating all the possibilities and events that could have lead to my stereo spoiling. This would prompt me to look for the known facts about my current problem. The first question would be doing other appliances work? The next question would be does my stereo behave this way, or this is an exception?
As a matter of fact, there are several factors that can lead to this problem and through scientific method; it is my duty to implement it and attempt to find a solution to my present problem. By establishing these answers, I would develop an initial hypothesis that can be of much help in establishing a solution to my problem.
My initial hypothesis would

My socket blew up because of a power surge mainly because it is a long time since I had replaced my sockets.
Testing the hypotheses
To determine the root of the problem, I need to test my hypothesis to ensure that I get the real problem before eventually evaluating my alternatives to ensure I get the best solution regarding effectiveness and efficiency.
The first test would use an alternative socket to determine if actually, my socket blew out. If the radio works, it is clear that the socket must be the cause of the problem. However, if it fails, I need to go to the next hypothesis.
The second hypothesis may be a bit difficult to test because it may require the stereo to be taking to an electrical and electronic expert to check on its capacitors to determine the problem. If the radio works in this scenario, one thing should be clear for sure, that it had blown out in the course of the day due to a power surge.

• Then the fault cable is tested to determine the type of fault, 18 KV is applied on each phase for 5 minutes, if the phase can carry this voltage, so this phase is good and no fault on it, if the phase cannot withstand this value of voltage, this means that the insulation is damaged and this phase is faulty, If one or more phase cannot withstand the 18 KV then these phases are faulty and the type of fault is short circuit due to breakdown of the insulation, but if the phases withstand the 18 KV applied but the current from the sending end not reach the other end, this means that there is an open circuit fault which is may be break in the conductor or the joint connecting the
7.4.1.1 Dielectric withstanding voltage The purpose of this test is to prove that a connector can operate safely at its rated voltage and will be able to withstand momentary over potentials due to switching, surges and other similar phenomena. The applied voltage can be either AC or DC. The voltage should be applied across the two closely spaced contacts as well as between a connector shell and the contacts closest to the shell. The test voltage in the case of coaxial connectors shall be applied between the inner and outer conductor. The voltage should be ramped up uniformly from zero to rated value.
If it malfunctions you malfunction.
Evidence base practice (EBP) is a proactive methodology to improving patient care. Nurses are now called upon to research, identify and analyze practice problems so that questions can be answered on how to deliver care. Therefore, the translation of research into practice require strategies such as protocol and guideline to disseminate EBP within an organization (Yoder-Wise, 2015). By researching barriers to breastfeeding in the neonatal intensive care (NICU), policy changes are noted to be indicated.

To establish the projects successfulness a set of tests were conducted, these tests observe and analyse every part of the prototype setup. The results to these tests are compared against the project aim and consequently are used to formulate a conclusion top the project. As set out in chapters 2 and 3 both the electrical/electronic and mechanical systems must meet a set of requirements; these requirements are based on the project objectives and deliverables. The tests conducted measure the prototypes adherence to these requirements, the tests provide data that can be formulated and examined to establish the functionality of each system. There are three types of tests carried out within this project, preliminary testing, functional testing and characterisation testing; each of type of tests examines the system in a greater depth than the preceding test type with characterisation testing being the most in-depth.
Some of the Low noise amplifiers, such as the OP37GPZ and the TL071CN need to be tested before it is put into the circuit. Sometimes, there are short circuits between pins and if put in the circuit, one will see that the operational amplifier drawing current from the power supply. To avoid such problems, a multi-meter can be used to test whether each pin has continuity or not. If it has continuity, then the operational amplifier is damaged. It was found out that during the implementation of the experiment, the OP37GZ had a short circuit on two of the pins.
Career Episode 3 Scenario – 1 XYZ Ltd has the specialty to build and provide the maintenance for Underground communication equipments and recently they received the signal boosters having the problem with DC power supply and gain. You are working as a technician and your manager asked you to write down the report by testing two circuits and devices below by using different testing procedure and provide the detailed observation. P1.1 Your report/observation must contain the following information. 1) Test the semiconductor devices used in the both circuits in figure 1 and figure 2. 2) Record the measured voltages, currents at different points and suggest about correct functionality.
It is very important that you check the engine properly because if you find any major problem later on, the repairs can cost a fortune. There are some important things you want to especially check under the bonnet like check for leaks, check for oil, etc. You can remove the oil filter cap and check if everything is fine. Check for any loose wires and other possible wears and tears.
Moreover, they also need to know how to replace spark plugs. Their main goal is to help keep cars running spectacular. The first step in fixing car problems is to ask the owner what sounds do they hear or how it runs.
Not to worry though, because sometimes, a CEL can illuminate because of the simplest of reasons. Learning more about the one in your Cadillac STS gives you the upper hand in knowing what actions to take. When the Check Engine Light comes on, one or multiple diagnostic trouble codes (DTC) are stored in the engine control module, which is stored even after the light goes out. Determining the problem starts with retrieving the DTCs, deciphering what each code conveys, before moving on to the actual troubleshooting.
Figure 4.26 Total, potential and critical transformer energies for 0.1 second fault at bus 28. Figure 4.27 Transformer 9-29 energy and critical energy. In contrast with the AC system, generators 14 and 13 go unstable after the separation of generator 9 and then they are followed by generator 16. This response confirms case 5 conclusion that the existence of the nearby HVDC line 50-51 has a great impact on the stability of the three equivalent generators 14, 15 and 16.
In order to serve this purpose, the following research questions are
