What is a capacitor connection?

Circuit Connections in Capacitors - In a circuit, a Capacitor can be connected in series or in parallel fashion. If a set of capacitors were connected in a circuit, the type of capacitor connection deals with the voltage and current values in that network.

Why should a capacitor be connected in series?

Connecting them in series increases the voltage capability (add voltage limits of all caps in series). To have robustness against short circuit specially ceramic capacitors that are connected to power lines. If capacitor shorts, it can burnt PCB trace or worst it may cause fire.

How does a capacitor reduce line current?

By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load. Reduced current also significantly lowers the I 2 R line losses. Capacitors provide a voltage boost, which cancels part of the drop caused by system loads.

What happens if a set of capacitors are connected in a circuit?

If a set of capacitors were connected in a circuit, the type of capacitor connection deals with the voltage and current values in that network. Let us observe what happens, when few Capacitors are connected in Series. Let us consider three capacitors with different values, as shown in the figure below.

How does a capacitor provide power?

Capacitors provide power just when reactive loads need it. Just when a motor with low power factor needs power from the system, the capacitor is there to provide it. Then in the next half cycle, the motor releases its excess energy, and the capacitor is there to absorb it. Capacitors and reactive loads exchange this reactive power back and forth.

Do you need a capacitor in a high voltage circuit?

Capacitors have a maximum voltage they can take before the dielectric (or vacuum) inside of them breaks down and starts conducting. Thus, if you need to have a capacitor in a high voltage circuit it may be necessary, or just more convenient, to place them in series.
