resistors

Over time, the capacitor will discharge through R to the point where the SCR turns off, and this subsequently closes the transistor and the uC detects this to perform some action. When R = 100kohm, it takes about 6 minutes for the cap to discharge and all the other stuff in the micro to start. When R = 120kohm, the cap does not discharge at all.

8.1 Capacitors and Capacitance

Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.If the charge changes, the potential changes correspondingly so …

How to Charge a Car Audio Capacitor (Step by Step Guide)

To charge the capacitor, connect the negative wire of the charging tool to the negative terminal of the capacitor and vice versa. After that, wire the capacitor''s positive terminal to the car battery''s positive terminal and connect the capacitors negative terminal to the car''s ground chassis, but not where the amplifier is grounded.

If you disconnect the power, the capacitor keeps hold of its charge (though it may slowly leak away over time). But if you connect the capacitor to a second circuit containing something like an electric motor …

electric circuits

Capacitors always take time to charge. In practice, when a capacitors is ~99% charged, we can call it fully charged. The exponential which is used to describe the charging of a capacitors does not make sense when time is very large because charge can never be less than charge of an electron while in the exponential equation, for a …
