When connected to a 120 V outlet, a light bulb consumed a power of 50.4 watts. What is the current flowing through it?

Given dа ta:

Voltage (V) = 120 V,

Power (P) = 50.4 Watts,

current flowing (I) = ?

Power is nothing but the rate of doing work. Hence W/t represents electric Power (P).

Electric Power (P) = V. I Watts

This equation can be used to calculate the power consumption by any electrical device that is connected in a circuit.

In the given question, we need to determine the Current flowing through the circuit (bulb).

From the equation,

P = V. I Watts

50.4 = 120 * I

I = 50.4/120

I = 0.42 Amp

Current flowing through the circuit is 0.42 Amperes.
