Electronics in easy words
This section cover question about what is basic electronics, what is use of different parts of electronic, circuit design fault and fundamental theory of electronics. solution of some critical circuits and hits and tips of electrical theory.
A varistor is an electronics component with an electrical resistance that varies with applied voltage. Also known as a voltage-dependent resistor (VDR), it has a non-linear, non-ohmic current characteristic that…
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…
A short circuit is an abnormal connection between two nodes of an electrical circuit designed to be at different voltages. This results in an electric current limited only by the…
Resistor can 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:…
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…
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…
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….
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,…
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…
