if you have any doubt ,ask me

Answer 2

$\huge\textbf\red{Answer :}$

$\huge\textbf{E = 6 kWh}$


$\textbf\red{Solution :}$

According to question we have given;

Power (P) = 100 W

= $\dfrac{100}{1000}$

= 0.1 kW

Time (t) = 4 hrs.

Now,

E = P × t

= 0.1 × 4 = 0.4

We have to find energy consumed in 15 days

So,

Energy consumed in 15 days = 0.4 × 15

= 6 kWh.
