Electrical Power

Rate At Which Electrical Energy Is Delivered To A Load Is Called As Electrical Power .

The Unit of Measurement of Electrical Power is Watt & Power Symbol is Capital (P).

In Electrical Circuits Power is Equal to Current.

Power=I(P=I)

& Multiplied By Voltage

Power= I×V(I×E)

Therefore 1 Watt of Power is The Result of 1Ampere Of Current Driven By a 1 Volt Force Given by Circuit.

Example:- 

So if a Heater Takes 4 Ampere at 250 Volts.

How Much Power Does it Consume .

V× I=P

250×4=1,000

1Kilo-Watt
