Do capacitors consume electricity in circuits
$begingroup$ Correct me if I am wrong, but how does the capacitor pass current when it is in series with an AC signal source? The current "passes" but not in the way that you expect. Since the voltage changes sinusoidally, the voltages also changes across the capacitor, which gives rise to an EMF that induces a current on the other …

What Does a Capacitor Do | Explanation | Albert Resources
What Does a Capacitor Do? A capacitor is a device that stores electrical energy for a short time. Capacitors consist of two metal plates with a material called a dielectric in between. When connected to power, these plates hold opposite electrical charges. Later on, the capacitor can release this energy into the circuit.
Power Factor Correction (pfc) Tutorial
False! Adding a capacitor reduces the impedance Z and thus increases the supply current: I_supply = V_supply/Z. Improving the Power Factor to unity is the same has making the circuit resonant (i.e. X_total = 0) which allows the circuit to consume/deliver more power. This is of course what one wants for electric motors.

Now, since the distance is doubled, to get a final voltage equal to the battery that charges it, the electric field only needs to be 1/2 the electric field of the single capacitor. Since the electric field is proportional to the charge density, you only need 1/2 the charge density that would be on the single capacitor, so C = (Qsingle/2)/V.

How do capacitors work?
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
