Options :
- Electric Current
- Electric Power
- Electrical Resistance
- Electric Charge
correct answer : c)
Explanation :
Ohm (Ω) is the SI unit of electrical resistance. It measures the opposition offered by a conductor to the flow of electric current. Electric current is measured in amperes, electric power is measured in watts, and electric charge is measured in coulombs. Therefore, electrical resistance is the correct answer.
