End of the lessons, student should be able to ; • 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

  3. Circuit of process charging and discharging

  4. When switch to A : CHARGING PROCESS CURVE t = 5

  5. FORMULA FOR CHARGING PROCESS 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/ )

  6. FORMULA FOR CHARGING PROCESS e. Initial rate of change potential difference dVc = V / CR dt f. Time when capacitor fully charge t = 5 g. Energy stored, E = ½ CVmax2
