Question

The charge flowing in a conductor varies
with time as Q = at- bt2. Then which of the
following is not
1
The current decreases linearly with
time.
2
Current reaches a maximum and then
decreases.
3
a
Current falls to zero after time t = 2b
4 Current changes at a rate - 2b.​

Answer 1

Explanation:

The charge flowing in a conductor varies with time as Q = at - bt2. Then, the current (a) decreases linearly with time (b) reaches a maximum and then decreases (c) falls to zero after a time period t = a/2b (d) changes at a rate -2b Read more on Sarthaks.com - https://www.sarthaks.com/553080/the-charge-flowing-in-a-conductor-varies-with-time-as-q-at-bt-2-then-the-current
