These charge controllers will be control the output voltage and will protect the battery from overloading and will protect the wind/solar units from reverse voltage flows. The outputs of charge controllers will be connected to batteries. These batteries will be connected together in series or parallel. The outputs of the battery will then fed to the grid tie inverter and because of specialized functions of it as I explained before in the inverter
An increment of 3cm for every x coordinate (x=0, 3, 6, 9, 12, and 15) and voltage readings of .25, .30, .50, .75, and 1.00 will be measured. Below are two tables (because two different metal plates are used) of data that illustrate the voltage readings collected during the experiment. The readings on the voltmeter measure the electric potential of two different charge distributions and this measurement can be used to find the electric field. Electric field lines starts on a positive charge and end on a negative charge. The number of electric field lines tells us the amount of
3. Explain why the circuits works? It converts AC voltage to DC voltage. Current flows through the diode in one direction, showing only the positive half-wave on the oscilloscope. The negative half-wave is suppressed, while the positive half-wave appears across the load.
Early measuring instrument for small electric currents consisted of coil of insulated copper wire wound on a circular non-magnetic frame. Working based on the principle of the tangent law of magnetism. Galvanometer works on the principle of conversion of electrical energy into mechanical energy. When the current flows in a magnetic torque. Galvanometer has a word called sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from a mirror.
2.1(a)): as the gray accelerometer box moves from side to side, the mass (which is a red blob) is left behind and the spring connecting it to the box (red zigzag) soon pulls it back into the position and, as it moves, it draws a trace (blue line) on the paper. Fig.2.1 (b) Capacitive Accelerometer Alternative designs of accelerometers measure force not by making a pen trace on paper but by generating electrical or magnetic signals. Capacitors can be used in accelerometers to measure force in a similar way as that of mechanical ones: if a moving mass alters the distance between two metal plates, measuring the change in their capacitance gives a measurement of the force that’s acting on it. The broad concept of capacitor based accelerometer can be understood from the above figure (Fig.2.1 (b)). In some accelerometers piezoelectric crystals such as quartz do the clever work.
If the wire is long and thin, when a current is sent through the wire a uniform magnetic field forms inside the solenoid. When the electric current flows through the wire the solenoid generates a magnetic field similar to that of a bar magnet. An electromagnet is a magnet whose magnetic properties are produced by an electric current. When the current is switched off, the electromagnet no longer displays magnetic properties. Another definition for electromagnets are solenoids wound around a central iron core.
- The proposed topology and control strategy reduces the positive DC-bus current ripple. This will reduce the ripple experienced by a battery source, feeding the inverter. As the topology and the control scheme achieves balanced DC-link voltages without using conventional capacitor balancing algorithms, the topology avoids additional switching instances associated with the conventional algorithms. This provides the topology an additional degree of freedom to use various switching loss reduction schemes. VII.
Celery started with a pH of 6.05 and dropped down to a pH of 5.03 after 30 drops that is not nearly as drastic as alka seltzer. But, it shows how celery does not have a buffer because of the drop in pH and is not able to create more hydroxide ions when acid is added. Liver started with a pH of 6.50 and after 30 drops the pH dropped down to 6.03 which means the drop in pH is only .47 and looks similar to the data of the positive control of alka seltzer. The data in this lab follows the hypothesis of testing the HCI of liver and celery, then liver will contain a buffer and celery will not. This conclusion can be drawn because of celery’s large drop in pH and the data’s resemblance to the water data meaning celery cannot hydrolyze ions and keep a constant pH.
Explain in details. For protecting the sensitive data access to the unauthorized users via electromagnetic emanations we use different counter measures. The first and most important counter measure is shielding. It is special type of shielding material that does not let any emission to come in and go out. The standard used for electromagnetic security is known as TEMPEST.
2.4. Stainless Steel Stainless steels are described as an iron base alloy, where it is called as inox or inox steel. Stainless steels are steel alloys which contain minimum 10.5 percentage of chromium content. On the surface of stainless steel a thin dense chromium oxide film will form to provide corrosion resistance and further prevents oxidation. Stainless steel is an inoxydable which means it can’t be readily oxidized (incapable of rusting).
