Electrical energy used per second is given by
Correct answer: D. all of these
- A. VI
- B. I^2R
- C. V^2/R
- D. all of these
Explanation
The electrical power P is given by P=VI, where V is the voltage and I is the current. Additionally, power can also be expressed as P=I^2R and P=V^2/R using Ohm's law (V=IR). Therefore, all of the options (a), (b), and (c) are correct representations of electrical energy used per second.Incorrect options: None. All options are correct.

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.
