Question

A current of 6.0 A runs through a circuit for 2.5 minutes.

How much charge was delivered to this circuit?

15 C
25 C
600 C
900 C

Answer 1

To calculate the charge delivered to the circuit, you can use the formula:

\[
Q = I \times t
\]

where \( Q \) is the charge in coulombs (C), \( I \) is the current in amperes (A), and \( t \) is the time in seconds (s).

First, convert the time from minutes to seconds:

\[
t = 2.5 \, \text{minutes} \times 60 \, \text{seconds/minute} = 150 \, \text{seconds}
\]

Now, plug the values into the formula:

\[
Q = 6.0 \, \text{A} \times 150 \, \text{s} = 900 \, \text{C}
\]

Thus, the amount of charge delivered to the circuit is **900 C**.
