Question

A charge of 12 C passes through an electroplating apparatus in 2.0 min. What is the average current?

Answer 1

The average current of an electroplating apparatus is = 0.1 A

How can we calculate that the value of the average current?

To calculate the average current of an electroplating apparatus, we are using the formula,

I=$\frac{Q}{t}$

Here we are given,

Q= A charge passes through an electroplating apparatus

= 12C.

t= The time within the current passing an electroplating apparatus

=2.0 min = 2.0×60 seconds=120 seconds.

Now we put the known values in the above equation,

I=$\frac{Q}{t}$

Or, I= $\frac{12}{120}$

Or, I=0.1 A

From the above calculation we can conclude that, the average current of an electroplating apparatus is = 0.1 A
