Question 272: Electrostats & Capacitance

Question

The charge on a capacitor plate in a circuit, as a function of time, is shown in the figure :

When is the value of current at t = 4 s ?

Accepted Answer

As we know, Current, $$I = {{dq} \over {dt}}$$
= Slope of q versus t graph
= Zero at t = 4s; (as graph is a line parallel to time axis at t = 4s)
