Quizplus · Accepted Answer

The power delivered to the lamp can be calculated using the formula P = V^2 / R, where P is power, V is voltage, and R is resistance. Assuming the voltage across the lamp is 12V (common for small circuits) and the resistance of the lamp is 12 ohms (a typical small value for illustrative problems), the power would be P = 12^2 / 12 = 144 / 12 = 12 W.
