Question

Find the electricity bill generated by a machine of power 500W used for 10 hours a day in the month of 30 days. The price for 1kWH= Rs.2

Pls Answer it Asap​

Answer 1

The electricity bill generated for the month would be Rs.300

-If the machine uses 500W power for 10hrs a day, then the energy used per day = 500 * 10 = 5000 WH

-Therefore for 30 days, the energy used is equal to 5000 * 30 = 150000WH

which is equal to 150 kWH

-If 1 kWH costs Rs.2,

Then 150 kWH costs 150 * 2 = Rs. 300
