The charge q on a plate of a condenser of capacity C charged through a resistance R by a steady voltage V satisfies the differential equation R(dq/dt) + q/c = V.If q=0 at t=0 then the expression for the charge on the condenser is?
A. q = CV(1 − cos−t/RC)
B. q = CV(1 − sin−t/RC)
C. q = CV(1 − e−ᵗ/RC)
D. q = CV(1 − cot−t/RC)
