First we have to convert 2.2kw into watt
So
1kw =1000w
2.2 * 1000=2200.0w
By using formula
R = v²/p
R= 220*220/2200
R=22 Ohm
So
1kw =1000w
2.2 * 1000=2200.0w
By using formula
R = v²/p
R= 220*220/2200
R=22 Ohm

Power, P = 2.2 kW = 2200 W
Voltage, V = 220 V
Time, t = 3 h = 3 × 3600 = 10800 s
So, the energy consumed is = 2200 × 10800 = 23760000 J
The current drawn is, I = P/V = 2200/220 = 10 A
Voltage, V = 220 V
Time, t = 3 h = 3 × 3600 = 10800 s
So, the energy consumed is = 2200 × 10800 = 23760000 J
The current drawn is, I = P/V = 2200/220 = 10 A
