The light bulb is connected to a 220 V network. If the current flowing through the coil of the lamp is 5 A, then the light bulb consumes energy equal to … kJ in 30 minutes of glow
By the condition of the problem, given:
U = 220 Volts.
I = 0.4 Ampere.
P-? Watt. (W)
Decision:
P = U * I
P = 220 * 0.4 = 88W. (W)
Answer: P = 88Watt (W).
