Answer 1

Answer:

ok let me help you

Explanation:

We have ,

power = 200watts and p.d. = 240 volts

from P=VI

200=240 × I

200÷240 =I

5/6=I

0.8333... amperes =I

Now,

E= P×T

E = 2.4 × 1

electrical energy consumed in 1 day = 2.4 kWh

cost of 1 unit of electricity = ₹ 3.50

electrical energy consumed in 30 days = 30×2.4

= 7.20 kWh

cost of 7.20 units of electricity = ₹ ( 7.20 × 3.50 )

= ₹ 25.2

hence the

1) electrical energy consumed in 30 days= 7.20KWh

2) cost of 7.20 units of electricity= 25.2

hope this helps

over and happy to help:)
