Question

An electrical appliance is rated 240 V, 500 W. How much current will this appliance draw? It is planned to spend Rs 200 for running this appliance in a month. If the per unit cost is Rs 4.60, how many hours can this appliance be operated in a month of 30 days?

Answer 1

Answer:

Simple.

load=800 watt.

Running hours per day= 6 hours

Daily consumption= 6 X 800= 4800 watt hour or 4.8 Kwh

Rate per unit= 3 Rs.

Daily Cost = 4.8 X 3= 14.4 Rs.

Monthly Cost= 14.4 X 30 = 432 Rs
