Question

An electric bulb of 60 W and heater of 940 W is used for 6 hr per day . if the cost of electricity is 3 ₹ per unit then calculate the electricity bill of one day​

Answer 1

According to the Question

Electric bulb = 60 W

Electric heater = 940 W

Total Power usage

= 940 + 60

= 1000 W

Change W in kwh

= 1 kwh

Time = 6 hours

Energy used = Hour × kwh

= 6 × 1

= 6

Rate per kWh = ₹ 3

Cost for one day = Rate per kwh × Energy used

= 3 × 6

= 18

Electricity bill of one day = ₹ 18

Answer 2

Answer:

Electric bill of one day = ₹18

Explanation:

According to the question,

Electric bulb = 60W

Electric heater = 940W

Total Power usage

= 940 + 60

= 1000W

Charge W in kWh

= 1 kWh

Time = 6 hours

Energy used = Hour × kWh

= 6 × 1

= 6

Rate per kWh = ₹3

Cost for one day = Rate per kWh × Energy used

= 3 × 6

= 18

Electric bill of one day = ₹18
