Solution

A resistor is an electrical component that implements electrical resistance as a circuit element.The current through a resistor is directly proportional to the voltage across the terminals of resistors.

Resistors are the most commonly used component in electronics which are used to create specified values of current and voltage in a circuit.They determine the flow of current in an electrical circuit and also they can be used with transducers to make sensor subsystems.
