Does a capacitor consume power?

ideally, it does not consume real power, but a reactive power of the circuit for the circuit

practically yes, it consumes a negligible power because of the resistance of contact or can in the arcs of commutation for inductance and internal loss for load capacitor). in alternating current, the energy is consumed during a half cycle when the voltage or the current increases and is restored when it decreases. they will not consume energy if they are ideal.

If you charge a capacitor, it will slowly lose its charge due to its internal resistance. The capacitor therefore consumes energy, but in practice it is negligible. Ideal capacitor does not consume energy.

The capacitor will heat up if it is not properly sized according to the circuit requirements. for this reason, a unipolar capacitor should be used.

Under ideal conditions, energy consumption is zero. he is absolutely right. do we have ideal conditions, especially during operation? the mosquito bat uses a capacitor to charge the high voltage. for a few minutes, it can produce a spark the next day, it is ineffective.

pour half a liter of water into a container and see what happens after a while. the water will be less than what you put. what happened. losses have prevailed. a capacitor is an electron container. like a mud pot, a metal pot and a porcelain pot, there are different varieties of capacitors and the losses vary. as in the fans, it heats up because it creates some opposition to the flow of electrons as a resistance.

according to the law of the ohms, when there is a resistance and that the current passes, it develops a tension through and the product of the voltage and the current is heat in Watts. heat is a loss of energy called energy consumed. in some places, the current and capacity are so low that you do not notice any heat, but there will be a small loss.
