An electric heater of 1000 W is working daily for 5 hrs in the month of September and the rate of 1 unit of electricity is ₹ 6.00, then the total cost and end of the month is ₹[[1]].

If an electric heater is rated

1000 W

is operated for

5 h ours

and cost of

1 unit

₹ 6

, then the cost of energy is ₹

900

.
It is given that the rating of the heater is

1000 W

and is operated for the time,

t = 5 h r

It is known that the energy consumption

(E)

is equal to

E = P \times t

Where

P, t

is the power and the time respectively.
On substituting the given values, we get

E = 1000 \times 5 \times 30

\Rightarrow E = 150000 W h

\Rightarrow E = 150 kW h

Since,

1 unit

1 kW h

and therefore energy consumed is equal to

E = 150 units

Hence, the energy consumed by heater is

150 unit

s.
The energy consumed by heater is

150 unit

and hence the cost of energy

(C)

is equal to

C = 150 \times 6 = ₹ 900

Therefore, the cost of energy is

₹ 900

An electric heater of $1000 W$ is working daily for $5 h rs$ in the month of September and the rate of $1 unit$ of electricity is $₹ 6.00$ , then the total cost and end of the month is ₹[[1]].
