Atoms become imbalanced by the loss or gain of atoms. When atoms loose these electrons, they are positively charged; when they gain electrons they are negatively charged. Once an atom stops being considered a neutral atom by either becoming a positive or negative atom, this creates static electr...

This causes an electromagnet to turn on, which activates the clutch, and mechanically connects the pulley and pump together. Automotive air conditioning systems consist of a few main components, which include a compressor, receiver/dryer, condenser, and evaporator. The system is charged with a ...
For example, when you push the button on a TV remote to watch TV, it sends an electrical signal to the “relay” inside the TV, turning the main power ON. There are various types of relays used in many applications to control different amounts of currents and number of circuits. Electri...
The microcontroller is a single-chip microcomputer that integrates the main part of the microcomputer on one chip. Microcontrollers are mainly used fo...
The AND and OR gates shown for diode logic are not complete in themselves; in addition to the fact that an inverter cannot be made without amplifying components, the lack of amplification limits the complexity of logic circuits that can be built with them. ...
Varactor diodes, also called varicaps, are semiconductor devices that behave like variable capacitors. When reverse-biased, they have a capacitance that varies with an applied voltage. They are most often used in devices that require electronic tuning, s
2. The structure of vacuum circuit breaker Vacuum circuit breakers are made up of three basic parts: a vacuum interrupter, an operational mechanism, a bracket, and additional components. 2.1Operating structure The vacuum circuit breaker uses an established and dependable electric energy storage spring...
Name an example of a non-contact force. What is super insulation? Name one device that uses an electromagnet. Why do resistors have tolerance? What is electrical susceptibility? Name the factors on which the heat produced in a wire depends when current is passed in it. ...
What is an electric motor? State its principle. Force In Motor: The physical force produced due to the motor is responsible for obtaining some useful work in the form of energy. The magnitude of force produced in the motor is equal to the product of the magnitude of the magnetic field, ...
