Question

A geyser is rated 1500W, 250V. It is connected to 250 V mains. Calculate the current drawn, energy consumed in 50 hours and cost of energy consumed at Rs.2.20 per kWh.

Answer 1

Answer:

Total cost =165 Rs. Hence, The current,energy consumed in 50 hours and total cost are 6 A, 75 kW-h and 165 Rs.

Answer 2

Answer:

166 ans

Explanation:

Power=Voltage×Current or P=VI

Here P=1500 Watts, Voltage=250 V

So I or Current=P/V=1500/250=6Ampere

2) Energy or Heat produced by electricity=Power×Time, or Energy=VIT

So energy=VIT=250×6×50=75000 Watt-Hour or 75 Kilo Watt-Hour

3) Cost=2.2 Rs/KWH

So total cost=75×2.2=165 Rs.
