If current is 3 A and voltage is 240 V, power is

Explanation:
Electric power in a circuit is found by multiplying voltage by current (P = V × I). With 240 V and 3 A, the power is 240 × 3 = 720 watts. This is the rate at which energy is being delivered. If either quantity were different, the product would change accordingly—for example, 360 W would require 1.5 A at 240 V, 480 W would require 2 A, and 1200 W would require 5 A. So 720 watts matches the given voltage and current.
