Resistance is the ratio of voltage to current. The symbol used for resistance is 'R'. In a circuit diagram resistance is represented by a zigzag line. It is an opposition to the flow of a current in a circuit. The resistance in a circuit is directly proportional to the applied voltage.
Voltage = Resistance * current
Resistance = voltage / current
The unit of resistance is ohm. If the voltage applied is one volt and one ampere current passes through the circuit, then the resistance in the circuit is one ohm.
Unit of resistance= Unit of voltage/ Unit of current
Unit of resistance = Volts/ ampere
Unit of resistance = Ohm
