If the current in an electric conductor is


If the current in an electric conductor is 2.4 A, how many coulombs of charge pass any point in a 30-second interval?

Solution:

I=2.4 A

t=30 s

 

The number of coulombs of charge passing a point is equal to the current multiplied by the time.

 

Q=(I)(T)

=(2.4)(30)

=72C
