Question

three bulbs of 60watt 230 volt each two fans of 60 watt 230 volt each one heater of 1000 W are used for 5 hours daily calculate the energy consuming 30 days and the cost of it if the unit rate is rupees 5​

Answer 1

Explanation:

Energy = Power*time

Energy consumed by 100 W bulb per day = 2∗100 Wh

= 0.2 kWh

Energy consumed by 40 W bulbs per day = 4∗40∗4 Wh

= 0.64 kWh

Total energy consumed per day = 0.2 + 0.64 kWh

= 0.84 kWh

Therefore, the energy consumed in 30 days = 30∗0.84 kWh

= 25.2 kWh
