CBSE Class 12-science Answered
The charge flowing in a conductor varies with time t, as q = at - 1/2bt^2 + 1/6ct^3, where a,b and c are positive constants. Then find :- 1.)the initial current 2.)the time after which the value of current reaches a maximum value 3.)the maximum or minimum value of current
Please give the answer in proper and clear steps

Expert Answer
Charge flowing in the conductor is given by
current is given by
time for maximum or minimum value of current is given as
Further differentiation gives positive constant c, hence current is minimum at t= b/c
minimum current is given by
