Question
1. A capacitor C is charged to a potential V and then discharges through a resistor R. Starting with the equation for the resistor current as a function of time, derive the equation for the potential across the plates of the capacitor as a function of time, carefully defining all terms. 2. Rewrite the equation in question #1 by solving for time as a function of resistance, capacitance and the potential. Show all steps. 3. Show how we will find the RC (time) constant of the circuit by plotting time vs ln(V(1)/V)Explanation / Answer
Q = CV[1 - e^(-t/RC) ] ........use this equation to solve it........
