Consider a simple electrical circuit where you charge a capacitor through a resistor by connecting a...

Consider a simple electrical circuit where you charge a capacitor through a resistor by connecting a battery (closing the switch) at time t=0. The charge Q on the capacitor is related to the current I by dQ/dt=I. Furthermore, by Kirchhoff’s law, V – RI – Vc =0, and the charge Q on the capacitor is Q=CVc, where C is the capacitance. That can be combined to give the differential equation dQ/dt = V/R - Q/RC The analytic solution is Q(t)=CV(1...
