Question

An electric geyser rated 1500w and 250v is connected to a 250v line mains.
Calculate:-
1 ) the electric current drawn by it.
2 ) energy consumed by it in 50 hours.
3 ) cost of energy consumed if each unit costs rupees 6.00

Answer 1

Answer:

P= 1500w

v = 250

T = 50H

Explanation:

1- P = VI

1500 = 250* I

1500/250 = I

I = 6 A

ELECTRIC CURRENT = 6A

2- E = PT

E = 1500* 50 = 75000wh

ENERGY= 75000WH OR 75 KWH

3- (if the cost is per kwh then)

cost = 75*6 = 450rs
