Transcript of PROCESS OF CHARGING AND DISCHARGING IN A CAPACITOR
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 , = CRb. Initial Charging current I max = V/Rc. 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 dtf. Time when capacitor fully charge
t = 5g. Energy stored, E = ½ CVmax2
a. Time constant , = CRb. Initial disharging current I max = V/Rc. 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 dtf. Time when capacitor decrease
charge
t = 5
