Capacitor Charging

To charge a capacitor, a power source must be connected to the capacitor to supply it with the voltage it needs to charge up. A resistor is placed in series with the capacitor to limit the amount of current that goes to the capacitor. This is a safety measure so that dangerous levels of current don''t go through to the capacitor.

Charging and Discharging Capacitive Circuits Detailed Explanation

Charging the Capacitor. The capacitor will start to charge when S1 is closed while S2 remains open as Figure 32. At this instance, the sum of the current in the resistor and the capacitor is always equal to zero. This is due to the 180 degrees phase difference between the two currents. If we define the resultant current algebraically, it will be

Capacitor Charging and Discharging Equation and RC Time

Q i is the initial charge stored on capacitor terminals which causes the initial voltage on its terminals v i.. Now we are connecting the above capacitor to a circuit with source voltage E. There will be a difference between the source voltage and capacitor voltage, so the capacitor will start to charge and draw current according to the difference in voltage.

Now we need to figure out what happens during the time period when a capacitor is charging. We start with the most basic case – a capacitor that is discharging by sending its charge through a resistor. We actually mentioned this case back when we first discussed emf. As we said then, the capacitor can drive a current, but as the charge on the capacitor neutralizes itself, the current

The voltage across the capacitor for the circuit in Figure 5.10.3 starts at some initial value, (V_{C,0}), decreases exponential with a time constant of (tau=RC), and reaches zero when the capacitor is fully discharged. For the resistor, the voltage is initially (-V_{C,0}) and approaches zero as the capacitor discharges, always following the loop rule so the two voltages add up to
