Electrical Power Calculation

What is the current flowing through the circuit?

Given data:

Voltage (V) = 120 V,

Power (P) = 50.4 Watts,

Current flowing (I) = ?

Answer:

Using the formula for electrical power:

Electric Power (P) = V.I Watts

We can calculate the current flowing through the circuit:

50.4 = 120 * I

I = 50.4 / 120

I = 0.42 Amp

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

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

Therefore, the current flowing through the circuit is 0.42 Amperes.
