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 can cause an increase in resistance. A resistive…

What is a pure inductor?

Inductors do not behave just like resistances. While the resistors simply oppose the flow of electrons through them (by lowering a voltage directly proportional to the current), the inductors resist…

Why do you use a resistor with an LED?

When you talk about resistor with LED then first in your mind got Why do you need an LED resistor? Resistor used in LED to limit the LED current to…

What do you use a resistor for?

Resistor┬ácan be used to reduce the voltage or current available in a circuit by adding resistance between 2 components of circuit. The role of the resistor in an electrical circuit:…

What is the resistor colour code?

Resistance values are often indicated by color codes, Resistor color code is identification of that resistor’s resistance, some resistor is very small in size and some very big but its…

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 circuits, resistors are used to reduce current flow, adjust…

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 resulting from an overload or a short circuit….

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 is very fast. In other words,…

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 engine. The start and run…
