An electric resistor is a two-terminal passive component specifically used to oppose and limit current.

A resistor works on the principle of Ohm’s Law which states that voltage across the terminals of a resistor is directly proportional to the current flowing through it.

Ohm’s Law: V = IR

where V is the voltage applied across resistor,I is the current flowing through it,and R is the constant called resistance.

The unit of resistance is ohms.
