>>In units..
Energy=power×time
=2.5 Kw×4h
=10 Kwh or 10 units.

.Power rating of the electric oven = 2500 Watts
Time for which the electric oven is On = 4 hours = 4 × 60 × 60
Time for which the electric oven is On (t) = 14400 seconds
Power is defined as the rate at which the energy is consumed.
Hence, the formula for power is:
Power = \frac{Energy}{t}Power=tEnergy
Energy consumed = Power × t
Energy consumed = 2500 × 14400
Energy consumed = 36000000 Joules
Hence, the energy consumed by the electric oven in 4 hours is 36000000 Joules.
