A capacitor charges to 63% of the supply voltage that is charging it after one time period. After 5 time periods, a capacitor charges up to over 99% of its supply voltage. Therefore, it is safe to say that the time it takes for a capacitor to charge up to the supply voltage is 5 time constants. Time for a Capacitor to Charge = 5RC
Charging a capacitor is not instantaneous. Therefore, calculations are taken in order to know when a capacitor will reach a certain voltage after a certain amount of time has elapsed. The time it takes for a capacitor to charge to 63% of the voltage that is charging it is equal to one time constant.
This is clear from your equation: the charge time is ≈ t ≈ 5 R C so if R = 0 R =, then t = 0 t =. However, batteries are not perfect voltage sources. They have an effective resistance, which is on the order of 1 ohm, so the time to charge your capacitor without a resistor is approximately
As a capacitor can be charged, it can also be discharged by replacing the battery in the electric circuit. The time for discharge follows analogous, where the time constant correlates to the charge percentage drop of about 37%. Similar to the charging, the discharging follows an exponential curve as the flowing current decreases over time.
So, the charge time of a capacitor is primarily determined by the capacitor charge time constant denoted as ? (pronounced tau), which is the product of the resistance (R) in the circuit and the capacitance (C) of the capacitor.
It is usually considered that five time constants are enough to charge a capacitor. For this circuit: When the everything starts out at 0 V and then the input is changed to Vin at time t=0: out() = in(1 − t RC) V o u t () = V i n (1 − − t) When R is in Ohms and C in Farads, then t is in seconds. There are TWO cases, as Chris indicated.
