Can I connect a capacitor to a power source directly?
$begingroup$ The easiest thing is to discharge the cap with a resistor, set the supply output to zero volts (or turn it off) and then connect the capacitor when both are at 0 V. Then you can turn on the supply and hopefully it will come up OK with the capacitor there. Lab supplies generally seem to do fine.
Get PriceCapacitor in Electronics
Capacitors with AC and DC. Capacitors behave differently depending on whether they are in direct current or alternating current situations: Direct Current (DC): When connected to a DC source, a capacitor charges up to the source voltage and then acts as an open circuit. This blocks any further DC current.

What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
