Detailed Solution

An electric bulb of

100 W

works for

4

hours a day. The units of energy consumed in

15

days in

kWh

is calculated as

6 units .

E = P \times t

Where

P

is in

kW

and

t

is in hours
If

P

is in Watts, the relation would be changed to

\Rightarrow E = \frac{Pt}{1000}

\Rightarrow

= \frac{100 \times 4 \times 15}{1000}

\Rightarrow E = 6 kWh

\Rightarrow E = 6 units

[as

1 unit = 1 kWh]
