For a 1 kw resistor and a 1000 uf capacitor the time constant should be 1 second. A charged capacitor can then be discharged by draining. Lab 4 Charge And Discharge Of A Capacitor Capacitor Discharging Graph Iamtechnical Com Charging Curve Of A Capacitor Charging and discharging of capacitor charging and discharging of capacitor. Charging and discharging time of capacitor . So one time constant for an rc disgharge circuit is given as the voltage across the plates representing 37 of its final value which will be zero volts fully discharged. The exponential the exponential voltage function which is derived from equation 1 vt v 2 o e t is shown in figure 3. You would have ample opportunity to learn more about it through the experiments that follow. From equation 53 it can be seen that rc is the time during which the charge on the capacitor drops ...
