What is Resistor? Function of the Resistor

A resistor is a passive electrical device with two terminals that interrupts the flow of electricity in an electrical circuit.

The resistor interrupts the flow of electricity in the circuit and at the same time drops the voltage in the circuit. The religion of the resistor is called resistance. The function of the resistor is to provide the required voltage to different components by controlling the current flow in different paths of the circuit.

The unit ohm of resistance. Its symbol is 6. Ohms are much smaller, so kilo-ohms and mega ohms are also used. The current rating is also given in the specification of the register. For example 1/4 W, 1 / 2W, 1W, 5W, or 10 W, the more watts, the greater the current-carrying capacity and the larger the size.

The amount of current that will interrupt depends on its quality and material. Resistors are made of different materials, but most are made of carbon. Carbon resistors are small and thin. The resistor has two terminals at both ends. The terminals are connected in two circuits.
