A charge of 12 c passes through an electroplating apparatus in 2.0 min, then the average current is 0.1 ampere.
Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge.
Electric current is defined as the charge per unit of time.
The mathematical relation between current and the electric charge
I =Q/T
where I is the current flowing
Q is the total electric charge
T is the time period for which the current is flowing
As given in the problem A charge of 12 c passes through an electroplating apparatus in 2.0 min
Let us first convert the time period of minutes into seconds
1 min = 60 seconds
2 min = 2*60 seconds
=120 seconds
By using the above relation between electric current and electric charge
and by substituting the respective values of the charge and the time period
I =Q/T
I = 12c/120 seconds
I = 0.1 Ampere
Thus, the average current flowing through the apparatus would be 0.1 Ampere.
