Question

A geyser is related 1500w. this geyser is connected to 250v mains.
1) the current drawn
2) the energy consumed in 50hr
3) the cost of energy consumed at rs. 2.20 per kwh

Answer 1

Power=1500w

Potential difference=250v

1)Power = V × I

1500 = 250 × I

1500/250=I

I = 6A

2) Time = 50h

E = POWER ×TIME

=1500 × 50

=75kWh

3)Cost = 75 × 2.20

= rs 165
