Correct formula to calculate Voltage (Voltage Formula) – Basic Electrical Engineering MCQ#45
The correct formula to calculate voltage is:
- V = WI
- V = P/R
- V = W/Q
- V = I.t
Correct answer: 3. V = W/Q
By definition the voltage is 1 volt if one joule of energy is required to move one coulomb of charge from one point to the other.
