Question

A current of 0.2a is drown by a filament of electric bulb for 5 minute. find the amount of electric charge?

Answer 1

Answer :

➥ The amount of electric charge = 60 C

Given :

➤ Current (I) = 0.2 A

➤ Time (t) = 5 min

To Find :

➤ The amount of electric charge (Q) = ?

Solution :

◈ Time (t) = 5 min = 5 × 60 = 300 sec

As we know that

⟾ Q = I × t

⟾ Q = 0.2 × 300

⟾ Q = 60 C

Hence, the amount of electric charge is 60 C.

➜ ampere-hour

Answer 2

$\star\:\:\:\large\underline\blue{Given:—}$

☛︎ current of the filament bulb, I = 0.2 A

☛︎ Time taken, T = 5 min

= 5 × 60 seconds

= 300 seconds

$\star\:\:\:\bf\large\underline\blue{To\:find:—}$

The amount of electric charge , Q = ?

$\star\:\:\:\bf\large\underline\blue{Solution:—}$

$\boxed{\bf{\red{Formula\:used:—Q=I×T}}}$

➝Q = I × T

➝Q = 0.2 × 300 C

↦Q = 60 C

Therefore,the amount of electric charge is 60 C
