The correct form of Ohm's law is:
Correct answer: C. V = IR
- A. | = VR
- B. P=IV
- C. V = IR
- D. Both Options B and C are correct
Explanation
Option C is correct since the statement of Ohm's law is obeyed by stating that V is directly proportional to me under constant temperature conditions. Secondly, V=IR is the correct formula for Ohm's law.Option A is correct since the formula I=VR given is wrong.Option B is incorrect since it alone is not sufficient.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
