VR C R E An R-C series circuit consists of a capacitor with capacitance, C, connected in series with a resistor with resistance, R. The resistance, R, is a circuit parameter that opposes the amount of electric charges Q, passing through the circuit per unit time and causes a drop in potential given by Ohm's Law while the capacitance, C, is a circuit parameter that measures the amount of electric charges that the current carries and stores in the capacitor. Both the resistor and capacitor cause the total drop in electric potential and is equivalent to the total electromotive force, E, which is produced by a voltage source such as batteries. E=+Rat As soon as the switch is opened, the initial charge Q, that is stored in the capacitor varies through time, t. In the given differential equation above, the charge Q and the time t are the dependent and independent variables, respectively. The electromotive force E, the resistance R, and the capacitance C are constants. Using A as the constant…
