Question

An electric bulb draws a current of 2 A when it operates at 220V.
Calculate the amount of electric charge flowing through it in 1 hour.​

Answer 1

Solution: It is given that an electric bulb draws a current of 0.2 ampere when the voltage is 220 volts.

Here,

Current, I = 0.2 A

Potential difference, V = 220 V

time = 1hr = 60 × 60 = 3600 s

As we know that,

Current, I = Q/t

where,

Q = Charge and t = time taken.

Using,

Current, I = Q/t

So,

Q = It

Q = 0.2 × 3600

Q = 720 C

Therefore, 720 C is the amount of electric charge flowing through it in one hour.

Answer 2

Answer:

7200 coulomb.

Explanation:

we know that:

$current(i) = \frac{charge(q)}{time(t)} \\ 2a = \frac{q}{3600sec} \\ q = 2 \times 3600 = 7200coulomb.$

Hope it helps you....
