Can the capacitor power supply pass through

Can I connect a capacitor to a power source directly?

It is fine to connect them when the output voltage of the supply and the voltage across the capacitor are close to each other. If they are not close to each other, you may get a spark at the moment you connect them. The spark can

Decoupling Capacitor vs Bypass Capacitor – Working

When the DC Power supply is delivering the power to the circuit the decoupling capacitor will have infinite reactance on DC signals and they will not have any effects on them, but it has much less reactance on AC signals so they can pass through the decoupling capacitor and they will be shunted to the ground If required.

Why Does A Capacitor Block DC But Pass AC?

Why Does a Capacitor Pass AC? When we connect a capacitor across an AC supply source, it starts charge and discharge continuously due to continuous change in the supply voltage. This is due to changes in AC voltage i.e. AC is positive in the initial cycle for "t = 1" and negative in the second cycle "t = 2" as shown in fig below.

How do I supply power through the GPIO?

First of all, using 5V GPIO pin you are bypassing input fuse that is on the RPi. This means you have no protection in case you make some short cut etc. So if you do, a lot of current (depending on how much you power supply can supply) can flow through your Pi and can damage it. You are also bypassing TVS diode so you are basically without any
