Question

a current of 3.8A flows in a wire for 12 minutes. how much charge passes through any point in this circuit during this time ​

Answer 1

Answer:

2736

Explanation:

t=12 x 60=720

I=Q/t

ie,Q=It

      =3.8 A  x  720

      =2736 Cu

Answer 2

AnswEr:-

Your Answer Is 2,736 Coloumb (C) of charge.

ExplanaTion:-

Given:-

• Amount of current flow in the wire = 3.8 A.

• Time for which the current flow in the wire = 12 minutes.

To Find:-

• The amount of charge pass through the wire in that time.

Formula Used:-

$\\ \tt\longrightarrow I = \dfrac{Q}{T}.$

Where,

• I = Current in amphere.

• Q = Charge in coloumb.

• T = Time in seconds.

So,

First we have to first convert 12 minutes in seconds.

$\\ \tt\longrightarrow12 \: \: minutes = 12 \times 60 \: \: seconds. \\ \\ \tt\longrightarrow 12 \: \: minutes = 720 \: \: seconds.$

Hence Here,

• I = 3.8 A.

• Q = ?? [To Find].

• T = 720 sec.

Therefore,

Lets put the value in above formula:-

$\\ \tt\mapsto I = \dfrac{Q}{T}. \\\\ \rm\mapsto 3.8A = \dfrac{Q}{720sec}.\\\\ \rm\mapsto Q = 3.8A \times 720 sec. \\\\ \rm\mapsto Q = 2,736 \:\:C.$

$\tt\therefore$ The amount of charge flow in 12 minutes through the wire in of 2,736 Coloumb.
