Question

If a current of 2 A flows through a wire of length 1 m for 1 min, the charge flowing through it during this time is

• A. 1 C
• B. 2 C
• C. 10 C
• D. 60 C
• E. 120 C

Hint:

Use: \[ Q=It \] Always convert time into seconds.

Answer 1

Answer: (E)

Charge flowing is: \[ Q=It \] Given: \[ I=2\text{ A} \] \[ t=1\text{ min}=60\text{ s} \] So, \[ Q=2\times 60=120\text{ C} \]
Hence, the correct answer is: \[ \boxed{(E)\ 120\text{ C}} \]
