Answer 2

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) ofelectricity

1 unit of electric energy in electricity bill is eqaual to 1 kWH
amd,       1kWh = 3600000 joules = 3.6 X $10^{6}$
