Question

A total charge of 2.5 × 10-3 C passes a point every 40 seconds. Calculate the value of the current through the point.

Answer 1

I =62.5 μ A

Step-by-step explanation:

Given that

Charge ,q = 2.5 x 10⁻³ C

time ,t= 40 s

We know that current I given as

`I=(q)/(t)`

Now by putting the values in the above equation we get

`I=(2.5* 10^(-3))/(40)\ C/s`

We know that

1 A = 1 C/s

Therefore the current I will be

I=0.0000625 A

I = 0.0625 m A

The current in μ A will be

I =62.5 μ A
