What is the relationship between power, current and voltage?
Correct answer: B. P=VI
- A. P=V/I
- B. P=VI
- C. 2P=l+V
- D. All of them
Explanation
Option B is correct since the formula to calculate power is 'voltage x current'.

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.
