Energy = Power × Time
= 1000 Watt × 60 min
= 1000 Watt × 1 hr ……[∵ 60 min = 1 hr]
= 1 kilowatt × 1 hr ……..[∵ 10³ Watt = 1 kilowatt]
= 1 kWh
∴ 1 kWh of energy is consumed by electrical appliances.
= 1000 Watt × 60 min
= 1000 Watt × 1 hr ……[∵ 60 min = 1 hr]
= 1 kilowatt × 1 hr ……..[∵ 10³ Watt = 1 kilowatt]
= 1 kWh
∴ 1 kWh of energy is consumed by electrical appliances.
