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.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
