what is the power input to an electric heater that draw 3A from a 220V outlet​

Sagot :

Answer:

Assuming this is for AC power with a unity power factor (pf) = 1.0, since an electric heater is a purely resistive load, Power (P) = Volts (V) x Current (A) × pf, so P = 250V × 4A × 1= 1000W. The formula for DC power does not include the power factor, but would yeild the same answer.
