Electrical Power Formula:

The electrical power can be calculated from the two circuits such as AC circuits and DC Circuits. Hence for DC circuit Electrical power is P(W) in watts is equal to the current I(A) in Ampere and multiply the voltage V(V) in volts.Hence the Electrical power formula can be written as

P (w)= I (A)* V(V)

For AC Circuits, The power will be based on the input what we have given such as single phase and three phase

P=V * I * Power factor

Here P means, Power in Watts, I means, current in Amps and V means applied voltage. Also from that you can calculate the current flow or applied voltage,

I = P / (V * PF) Amps

V= P / ( I * PF) Volts

Example:1

Calculate the electrical power? In a current and voltage of an electric circuit are 4.5 A and 25 v respectively, the power factor is 0.85.

Answer:

Given that

Current I=4.5A

Voltage v= 25v

Power factor PF =0.85

The formula of Electrical power is p= I* V* PF

P=4.5 *25*0.85

P=95.625

Therefore, the electrical power consumed in the circuit is 95.625 watts.

Example:2

Calculate the electrical power? In a current and voltage of an electric circuit are 8.4 A and 24 v respectively, the power factor is 0.14.

Answer:

Given that

Current I=8.4A

Voltage v= 24v

Power factor PF =0.14

The formula of Electrical power is p= I* V* PF

P=8.4 *24*0.14

P=28.224

Therefore, the electrical power consumed in the circuit is 28.224 watts.
