Question

The domestic consumption of electrical energy is measured in kwh .Calculate the cost of using a 2kwh emmersion rod for heating water in a house for 1hr each day for 60 days if the rate is 2per kwh?

Answer 1

Answer :-

Cost = ₹ 140

Given :-

p = 2kwh

t = 1 h

Number of days = 60

Cost of electrical energy consumed = ₹2 / kwh.

To find :-

The cost of using the emersion rod.

Solution:-

The electrical energy consumed by emersion rod is given by :-

$\huge \boxed{E = p t n }$

Put the given values ,

→$E = 2 \times 1 \times 60$

→$E = 120 kwh$

Now,

The electrical consumed by emersion rod is 120 kwh.

1 kwh cost ₹ 2

120 kwh cost = 120 × 2

= ₹140

hence,

The cost of electrical energy consumed by emersion rod is ₹140.
