Question

please tell me the answer

Answer 1

Here First, we convert the time to seconds.

1 hr = 3600 seconds

Time = 2 × 3600 = 7200 seconds

Formulas :

Power = Voltage × Current

Power = 220 × 6 = 1320 watts

Energy = Voltage × Current × Time

Energy = 220 × 6 × 7200 = 9504000 Joules

= 9504 kJ

Therefore, the energy consumed by an electric heater in 2 hours is 9504 kJ.

i hope it will helps you friend
