The Correct Formula for Ohm’s Law is – Basic Electrical Engineering MCQ#30

The Correct Formula for Ohm’s Law is:

1. V = IR
2. V = R/I
3. V = I/R
4. V = P/R

Correct answer: V = IR

According to Ohm’s law the electrical current in any circuit is directly proportional to the resistance.

V ∝ I

OR

The voltage through any resistor is directly proportional to the product of current and resistance.

V = IR
