An electric iron has a rating of 750w,220v, calculate the current flowing through it and its resistance when in use

Asked by praveengupta2919.9 | 31 May, 2021, 02:53: PM
Expert Answer
Power = Voltage × Current
 
Current = Power / Voltage  = 750 W / 220 V = 3.41 A
 
Resistance = Voltage / Current = 220 V / 3.41 A = 64.53 Ω
