Question

90 Columbus of charge is passing through a conductor in 4 minutes what is the electricity current through a conductor​

Answer 1

Answer:

1. Time. 4 . 60 = 240

Explanation:

90/240=0.3

Answer 2

Answer: The correct answer is 0.375 Ampere.

Explanation:

Total charge flows in a conductor Q = 90 Coulombs

Time taken in flowing charge t = 4 minutes

Electric Current is the rate of flow of charge in a conductor.
The SI Unit of electric current is the Ampere. 
     
              Current = $I$ = $\frac{Q}{t}$ =Q/t

Here,

          Q = 90 C

           t = 4 minutes

           t = 4 x 60 seconds

           t = 240 seconds
So,

      Current = $I$ = $\frac{90}{240}$ = 90/240 Ampere

      Current = $I$ = 0.375 A

Thus, 0.375 A electric current passes through the conductor.

Note—Electrons are negatively charged particles hence when they move a number of charges moves and we call this movement of electrons as electric current.

Note—Conductors: these materials allow the free flow of electrons from one particle to another.
Conductors allow for charge transfer through the free movement of electrons.
