Answer 2

Answer:

Hey Mate here is your answer,

Ans-- Resistance = 440 Ohm .

Potential = 220 Volt .

Time = 10 hours

=> 10 × 60 => 600 minutes.

$\frac{energy}{time \: } = \frac{work \: done}{time} = power$

V = IR

$= > i = \frac{v}{r}$

$= > i = \frac{220}{440}$

$= > i = \frac{1}{2} \: a$

$i = \frac{q}{t}$

$= > q = it$

$= > \frac{1}{2} \times 600 \: = > 300c$

$v = \frac{w}{q}$

$= > w = vq$

$= > w = 220 \times 300$

$= > w = 66000 \: (ans)$
