Hi !
Current = I = 5 A
Voltage = V = 220 V
Power = P = ?
Time = T = 2 hr
Energy = E = ?
P = I × V
= 5 × 220
= 1100 W
E = P × T
= 1100 W × 2 hr
= 2200 W hr
= 2200/1000 kWh
= 2.2 kWh
( ∵ 1 kWh = 1000 W)
Current = I = 5 A
Voltage = V = 220 V
Power = P = ?
Time = T = 2 hr
Energy = E = ?
P = I × V
= 5 × 220
= 1100 W
E = P × T
= 1100 W × 2 hr
= 2200 W hr
= 2200/1000 kWh
= 2.2 kWh
( ∵ 1 kWh = 1000 W)
