Chapter 1, Problem 1P

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

To determine

The coulombs of the charge pass any point in a 30 -second interval.

The charge passes any point in a 30 -second interval is 72 C.

### Explanation of Solution

Given:

The current is 2.4 A.

The time is 30 s.

Concept used:

Write the expression for the charge.

Q=It   ...... (1)

Here, Q is the charge, I is the current and t is the time.

Calculation:

Substitute 2.4 A for I and 30 s for t in equation (1).

Q=(2.4 A)(30 s)=72 C

Conclusion:

Thus, the charge pass any point in a 30 -second interval is 72 C.
