Numericals:
2. The total electrical consumption per day is 10 kWh. Calculate the total electricity bill to be paid for 30
days when 1 unit of energy costs 6.10.
(Ans. 1830)
​

Answer 1

Given :

• Total electrical consumption per day = 10 kWh
• Total electricity bill to be paid for 30 days.
• 1 unit of energy costs = 6.10

To find :

• Total electricity bill paid for 30 days

According to the question,

➞ Electrical consumption per day = 10 kWh

➞ Electrical consumption in 30 days = 10 × 30 = 300 kWh

Now,

➞ Total electricity bill to be paid for 30 days = 300 × 6.10

➞ Total electricity bill to be paid for 30 days = 1830

So,total electricity bill to be paid for 30 days is Rs 1830.

Power :-

Power is defined as the rate of doing work.

• Power (P) = Work done (W) ÷ Time taken (t)

• When work is done,an equal amount of energy is consumed.

• Power is also defined as the rate at which energy is consumed.

• Power (P) = Energy consumed (E) ÷ Time taken (t)

Answer 2

Answer:

Given :-

• Total consumption of electricity = 10 kWh
• Total days = 30
• Cost of 1 unit of electricity = ₹6.10

To Do :-

Find total electricity bill

Solution :-

Firstly we shall find electricity bill for 1 day

Let's find

Electricity bill of 1 day = Total consumption × Total days

Electricity bill of 1 day = 10 × 30

Electricity bill of 1 day = 30 kWh

Now,

Finding total electricity bill for 30 days

Total electricity bill = Electricity bill of 1 day × Cost of 1 unit

Total electricity bill = 30 × 6.10
