Question: The plot represents the flow of current through a wire at three different times. The ratio of charges flowing through the wire at different times is (see figure)
Options:
A) 2 : 1 : 2
B) 1 : 3 : 3
C) 1 : 1 : 1
D) 2 : 3 : 4
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Charge = area under the current-time graph $ q _{1}=2\times 1=2,q _{2}=1\times 2=2, $ and $ q _{3}=\frac{1}{2}\times 2\times 2=2 $
$ q _{1}:q _{2}:q _{3}=2:2:2=1:1:1 $
