Question

करंट the charge flowing through the conductor various as q is equal to 3 t square minus 2 t find the current at the instant t is equal to 1 second

Answer 1

4 A

Answer 2

Given the charge $q(t) = 3t^2 - 2t$.
The current $i$ is the rate of change of charge with respect to time:

$$i = \frac{dq}{dt} = \frac{d}{dt}(3t^2 - 2t) = 6t - 2.$$

At $t = 1$ second,

$$i(1) = 6(1) - 2 = 4 \, \text{A}.$$
