Ic = (Vc/t)(c).
Perform Differentiation on the equation:
dIc/dt = (dVc/dt)----> (1).
Since dVc/dt = k then,
dIc/dt = k.

Yes, since the situation is 'voltage changes at constant rate' the current will be constant also because they are proportional with each other.

Voltage is constant C is constant Ic is constant with time.
But when Ic is C(dv/dt),
Then Ic is going to change with time to 5T.

Since voltage change with time, so overall ratio (v/t) will be constant. i.e current will be constant.

Since voltage is change with respect to time then we say that the over all ratio is (v/t) will be constant.

In case of capacitor the there will be no change in current for the sudden change in voltage.

Voltage changes at const rate means with time v/t will be const and hence I is const.

dv/dt=k then v=kt;
Substitute.. i=ktC/t;
i=kC;
i=constant;
Substitute.. i=ktC/t;
i=kC;
i=constant;
