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.

Capacitor in Electronics

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …

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.
