6. A circuit consists of a resistance R, capacitance C and constant electromotive force V. There is an initial charge Qo on the capacitor at t = 0. Let q denote the charge on the capacitor at time t. Explain the origin of the differential equation for q shown here and solve it using a method of your choice: dq V dt RC R Identify the behaviour of q as t becomes large in the solution and explain what this means in terms of the physical system being modelled
