Explain the process of charging and discharging based on the voltage and current curves. Determine the related equations for the voltage and current curves Formulate the instantaneous voltage / current equation. Determine the time constant, = CR Determine the energy stored in a capacitor. Solve problems on capacitors

t = 5

a. Time constant, = CR b. Initial Charging current I max = V/R c. Charging voltage of capacitor, Vc = Vmax (1 – e -t/ ) d. Charging current i = Imax (e -t/ )

e. Initial rate of change potential difference dVc = V / CR dt f. Time when capacitor fully charge t = 5 g. Energy stored, E = ½ CVmax 2

a. Time constant, = CR b. Initial disharging current I max = V/R c. Disharging voltage of capacitor,Vc = Vmax ( e -t/ ) d. Discharging current i = - Imax (e -t/ )

e. Initial rate of change potential difference dVc = V / CR dt f. Time when capacitor decrease charge t = 5
