Question

if 30 coulomb of electric charge flows through a wire in 2 minutes calculate the current in the wire​

Answer 1

Answer:

It's 15 ampere

Explanation:

Current=charge/time

=30/2

= 15 ampere

Answer 2

Given:

Electric charge= 30 coulomb

Time for which charge flows through a wire = 2 minutes = 120 seconds

To find:

Electric current flowing in a wire= ?

Step wise solution:

To calculate electric current understand the concept:

• An electric current is the flow of charged particles through the conducting material.

• The Standard International unit of electric current is Ampere or amp or A.

• One ampere is defined as flow of one coulomb electric charge in one second.

• It can be calculated as follows:

Electric current (Ampere) = Electric charge(Coulomb) ÷ time(seconds)

Electric current (A) = 30 C ÷ 120 s

Electric current = 0.25 Ampere

Hence, electric current is flowing at the rate of 0.25 C/s or 0.25 Ampere through a wire.
