    FAQs about Capacitors are connected without load

    What happens if a capacitor is connected on no load?

    Since when you connect the capacitor on no load, the reactive power should be consumed by nearby feeders, otherwise the source may affected by series voltage rising issues.

    Can a capacitor charge without a resistor?

    The capacitor is not charging to 5 V even when connected to a power bank without using any resistor and without any load at the output. Is a resistor always needed if we want to use a capacitor? Is a load always needed and will a capacitor only then start conducting?

    Can a capacitor be connected to a battery?

    Consequently, ideally there is an open circuit there. If you connect the capacitor to a battery, as no current can flow, each plate would ideally inmediately acquire the same potential as the battery. You know that conductors ideally adquire the same potential all along them (in electrostatics).

    Do I need a load to charge a capacitor?

    If the capacitor is empty, it will draw as much current as it can, more than what the powerbank can deliver, and the powerbank may protect itself from the overcurrent by turning the output off. Not necessarily, but in this case it will help to limit the current to what the powerbank can deliver. No, a load is not needed to charge the capacitor.

    What happens if you connect a capacitor to a supply?

    The wires that you use to connect the capacitor to the supply will in turn have their own resistance. These are important effects to take into account when you try and ask what happens in an extreme case, such as in your question. Ideally, a capacitor is made of two plates separated by an isolator.

    What happens when a capacitor is connected to a voltage source?

    When the capacitor is connected to the voltage source, current will flow from the source into the capacitor, causing a build-up of charge on the capacitor's plates. This process will continue until the voltage across the capacitor equals the voltage of the source.
