Question

A current of 5 A flows through a wire for 10 minutes. The total charge passed is: 

• A. 500 C
• B. 50 C
• C. 300 C
• D. 3000 C Correct Answer: (D) 3000 C Solution:

Hint:

Remember the basic relation: \[ Q=It \] One ampere means one coulomb of charge flows per second.

Answer 1

The Correct Option is D

Step 1: Use the charge relation.
Current is the amount of charge that flows each second, so the total charge is current times time.
\[ Q = I \times t \]

Step 2: Fix the units.
Time must be in seconds.
\[ t = 10 \times 60 = 600 \text{ s} \]

Step 3: Work out the charge.
\[ Q = 5 \times 600 = 3000 \text{ C} \]
\[ \boxed{3000 \text{ C}} \]
