Question

Calculate the electric energy consumed by an electric iron of 2200W in 30 minutes. *​

Answer 1

HERE IS UR ANSWER

Power= 2200W

Time= 30min, convert minute into second

30×60= 1800 sec

As, Power= work/ Time

then, Work = Power × time

work= 2200×1800

therefore, work= 3960000

work= 3.96 × 10⁶ joules

As work is equal to energy

therefore, ENERGY CONSUMED IS 3.96 × 10⁶ joules
