everyday science MCQ #49844

  1. Question 1

    Q1. The formula for electric power in terms of voltage (V) and current (I) is:

    • A) P = V + I
    • B) P = VI
    • C) P = V / I
    • D) P = V - I

    Answer: P = VI

    Explanation: Electric power is defined as the rate at which electrical energy is transferred, given by P = VI, where V is the voltage (potential difference) and I is the current. This formula can be combined with Ohm's Law to give the equivalent forms P = I²R and P = V²/R.
