Charging. As soon as the switch is closed in position 1 the battery is connected across the capacitor, current flows and the potential difference across the capacitor begins to rise but, as more and more charge builds up on the …
5.19: Charging a Capacitor Through a Resistor
Thus the charge on the capacitor asymptotically approaches its final value (CV), reaching 63% (1 -e-1) of the final value in time (RC) and half of the final value in time (RC ln 2 = 0.6931, RC). The potential difference across the plates …
Charging and Discharging a Capacitor
If the capacitor has a larger capacitance it means it can hold more charge, this means it will take longer to discharge. If the resistor has a larger resistance it means it is harder to move the …
