Answer:
Ohm
Explanation:
The devices that resists the flow of electric current are called resistors and they offer a resistance to the circuit.
1. Volt is the SI unit of voltage or potential difference
2. Coulomb is the SI unit of electric charge.
3. Ohm is the SI unit of resistance.
4. Watt is the SI unit of electric power.
5. Ampere is SI unit of electric current.
Hence, the unit to measure resistance of the circuit is ohm.
