A voltmeter shows a voltage of 12 V, an ammeter shows a current of 1.2 A. What power does a light bulb consume?

A voltmeter shows a voltage of 12 V, an ammeter shows a current of 1.2 A. What power does a light bulb consume? (ammeter connected in series, voltmeter in parallel)

Given:
U = 12 Volts – the voltage of the electrical network, according to the readings of the voltmeter;
I = 1.2 Ampere – the current consumed by the light bulb (according to the ammeter readings).
It is required to determine W (Watt) – the power consumed by the light bulb.
Since the condition of the problem is not specified, we assume that the ammeter and voltmeter do not consume power. Then:
W = I * U = 12 * 1.2 = 14.4 watts.
Answer: an electric light bulb consumes a power equal to 14.4 watts.
