Question
70 A current flows in a circuit. What is the time taken for 35 C charge to pass through the conductor.
- 0.5 s
- 2 s
- 70 s
- 35 s
Hint:
current is the rate of change of charge.
The correct answer is: 0.5 s
current = 70A and charge= 35C
time= charge/current= 35/70= 0.5sec
so, option 1 is correct
