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 data:

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.  

c) up is the direction the magnetic force is acting on the charge.
