Capacitor Discharge Time Calculator (with Examples)
Formula. V = Vo*e −t/RC. t = RC*Log e (Vo/V). The time constant τ = RC, where R is resistance and C is capacitance. The time t is typically specified as a multiple of the time constant.. Example Calculation Example 1. Use values for Resistance, R = 10 Ω and Capacitance, C = 1 µF. For an initial voltage of 10V and final voltage of 1V the time it takes to discharge to this level is 23 µs.
transistors
C1 charges in way +4.5v / Q2ec / C1 / Q1be so plus pole of C1 is at Q2 collector. Then after C1 is charged to 3.8V the both transistors are immediatelly closed so Q2 collector drops rapidly to almost 0V. During this the minus pole of C1 goes huge negative (-3.8v below ground at beginning) so C1 holds the Q1 base closed.

How A Capacitor Works
Just remember a capacitor takes time to charge (and discharge). 1. DISCHARGING A CAPACITOR. The discharge time for a capacitor is exactly the same as the charge-time. If it take 5 seconds for capacitor to charge from 1v to 7v, it will take 5 seconds to discharge back to 1v. The discharge curve is shown in the following diagram: 2. THE DELAY …
How does current flow in a circuit with a capacitor?
$begingroup$ Correct me if I am wrong, but how does the capacitor pass current when it is in series with an AC signal source? The current "passes" but not in the way that you expect. Since the voltage changes sinusoidally, the voltages also changes across the capacitor, which gives rise to an EMF that induces a current on the other side of the capacitor.

The bigger the capacity of your capacitor (i.e. more microfarads) the more energy it will store. In the above demonstration, if you have a small cap and a large cap, they will both charge to the same voltage when you touch them to the battery (1.5 volts or so), but the larger cap will take longer to discharge to 0 volts.

discharge
Initially SCR2 is triggered to charge the capacitor through the load. Once the capacitor has charged up to the supply voltage SCR2 will turn off when current drops below its holding current. If SCR1 is then triggered to power the load, the capacitor will discharge through the diode and inductor (which is now connected to V+ through SCR1).
How do capacitors work?
The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor.
