Answer 1

Answer:

(a)

$3.6 \times {10}^{6} \: joule$

Answer 2

Given - 1 unit of electricity.

Find - Equivalent of 1 unit of electricity in joules or watt.

Solution - 1 unit of electricity equals to 1 kiloWatt hour.

As we know, 1 kiloWatt is equal to 1000 Watt. Thus, option 2 and 3 can not be the correct answer.

Now, 1 kWh = 1000 Watt * 3600 second.

Hence, 1 unit = 1 kWh = 3.6*106 Joules.

Thus, the correct answer is(d) 3.6 * 10⁶ joues.
