4.11 Motor A DC motor is an electrical machine which converts electrical energy into mechanical energy. A magnetic field is generated by the current carrying conductor and when this system is placed in external magnetic field then the force is exerted which is proportional to the strength of the external magnetic field and to the current in the conductor, then motor will rotate. If the direction of current is reversed then the direction of rotation of motor will also reverse. The speed of DC motor can be controlled by the variable supply voltage or by changing the strength of current. Small DC motors are used in toys, tools, and appliances. Larger DC motors are used in propulsion of electric vehicles, in drives for steel rolling mills, elevator …show more content…
The MAX232 is a dual receiver/driver and it converts the TX, RX, CTS and RTS signals. The drivers provide RS-232 voltage level outputs (approx. ± 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors. The receivers reduce RS-232 inputs (which may be as high as ± 25 V), to standard 5 V TTL levels. These receivers have a typical hysteresis of 0.5 V and a typical threshold of 1.3 V. Figure 4.16: Pin Diagram of MAX232 4.13 RS232 Interface In telecommunications, RS-232 is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DCE (Data Circuit-terminating Equipment) and a DTE (Data Terminal Equipment). It is use to connect the computer serial port to the electronics component like data storage, printers, mice, un-interruptible power supplies, and other peripheral devices. The standard defines the meaning of signals, the electrical characteristics and timing of signals, and pin out of connectors and the physical size. Figure 4.17: RS232 4.14 Motor

The research assistant gave explicit demonstrations of how to use both base-10 block and unit blocks to construct two-digit number. First, the research assistant placed out ten unit-blocks in a line and then put a base-10 block along to the ten unit-blocks.

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.

168 Words | 1 Pages4.) I noticed that there is a relationship between the ionic radius and the atomic number of the representative elements in Group 1A. The higher the atomic number, the bigger the ionic radius is. So, while hydrogen has an atomic number of 1 and Francium has an atomic number of 87, it is safe to assume that FR has a higher ionic radius. This is true; the ionic radius for Hydrogen is 0.012, and for Francium, it is 0.194.

410 Words | 2 PagesWith widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.

1058 Words | 5 PagesBreak Point 6.2 I think that the students are trying to describe what most people cannot: the effect that music has not on our minds, but our bodies. Because the mind is not involved in this physiological process, one can only begin to describe why we get "pumped," why our heart rates increase or why our moods change when we hear a certain piece of music. In the conversation in Chapter 6, each student seems to have a different way of describing how music makes them feel, which supports my belief that each student has a unique physiological approach when listening to or performing music that is unlike that of anyone else. As the chapter mentions, there is no true explanation as to why some people get goosebumps when a certain song plays and others do not. Personally, my musical tastes are all across the board, and change

During this period, World War III happens with the two opposing sides are China and United States of America who are fighting for the ownership of the very limited resources on Earth. People would kill, steal, and rape others so that they can survive. Most people if not all have already lost their consciousness and sanity. However, a scientist named Sirloc is inventing a machine that hopefully will be able to solve the problem and bring peace back to Earth.

647 Words | 3 Pages1. Perception categories that significantly influenced walking frequency were landuse, and aesthetics and amenities. The safety, directness and continuity perception categories were not significant but had weak to moderate associations with land use and aesthetics perception. This implies improving perception of one category is bound to improve or negatively impact the perception of a correlated category. For example landuse perception was correlated with directness perception - which is intuitive, given that directness measured quick and easy access to land uses.

The Positive And Environmental Impacts Of Wind Energy
1838 Words | 8 PagesWind energy is currently one of the most popular sources of renewable energy due to it being inexpensive, currently competing in price with fossil fuels (Kim and Dah-Chuan Lu 2010). Wind turbines function by using the kinetic energy of the wind to drive the blades of the turbine causing the generator to convert the kinetic energy into electrical energy (Mahela and Shaik 2016). Horizontal axis turbines are the most common type of turbine. Figure 1 the setup of an air turbine with the two most common type of generators these are squirrel cage induction and doubly feed induction generators, with the doubly generators being preferred due to having control of synchronous speed (Wallace 2014).
