What is a capacitor used for in an electric motor? An engine capacitor such as a starter capacitor or a driving capacitor (including a dual-stroke condenser) is an electric capacitor…

What is the purpose of a capacitor in an AC circuit? During this charging process, a charging current (i) will flow to the capacitor opposite any voltage change at a…

What would happen to the voltage if you increase the resistance or what is varistor? A varistor is an electronics component with an electrical resistance that varies with applied voltage….

What happens to a resistor when it fails? A fixed composition resistor normally fails in an open configuration when overheated or too demanding due to shocks or vibrations. Excessive humidity…

What happens when a resistor is short circuited? A short circuit is an abnormal connection between two nodes of an electrical circuit designed to be at different voltages. This results…

What do you use a resistor for? Resistor can be used to reduce the voltage or current available in a circuit by adding resistance between 2 components of circuit. The role…

What is a resistor and how does it work? A resistor is a passive electrical component with two terminals that implements the electrical resistance as a circuit element. In electronic…

What does KA mean on a circuit breaker? A circuit breaker is an automatically actuated electrical switch designed to protect an electrical circuit from damage caused by excessive current, usually…

What is inverse time overcurrent relay? At this type of relay, operating time depends on the amount of drive. If the amount of drive is very high, the relay operation…

What is the current relay? The current start relays are used for motors with fractional power, which require a low starting torque. Its main function is to help start the…
