Question

A 1000W toaster is used every day for 30 min.how many units of energy will it consume in 30 days at the rate of ₹1.50 per unit​

Answer 1

Given:-

• Power of toaster = 1000W

• Time used = 30 min.

• Total days used = 30 days

• Rate of 1.50 Per Unit

To Find:-

• To Cost and Energy Consumed.

Solution:-

Conversion Of Unit

1 hour = 60min

30min = 30/60h = 1/2h

As we know that Energy is defined as the product of power and time .

• E = P×t

Substitute the value we get

→ E = 1000 × 1/2 × 30

→ E = 1000 ×15

→ E = 15000 Wh

→ E = 15000/1000 kWh

→ E = 15kWh

Now ,

1 kWh is also called 1 unit

15kWh is 15 units.

Rate Per Unit = 1.5

→ 15 unit = 15×1.5

= Rs 22.5

Therefore, the total cost of electricity is Rs 22.5 .
