Question

A GEYSER OF 2.5 KW IS USED OR 8 HOURS .CALCULATE MONTHLY CONSUMPTION.ALSO COST OF ELECTRICITY CONSUMED IN RATE OF 3.50

Answer 1

Daily Consumption of Energy=Power×Time
= 2.5×8=20 units
Taking 30 days in a month,
Monthly Consumption of Energy =20×30
=600 units
Cost=$3.5 per unit
=600×3.5
=$2100

Answer 2

Power = 2.5 kW
Time = 8 hrs.
Power = Energy / Time
Energy consumed = Power × Time
= 2.5× 8
= 20 kWh

Energy consumed in a month =20kWh × 30 = 600kWh

Cost of energy for 1 kWh = Rs 3.50
Total cost of energy for 600 kWh = 600 × 3.50 = Rs 2100
