### Is capacitor consume power?

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).

### How much average power is consumed by the inductor and the capacitor?

Average power consumed by capacitor and inductor is **zero**.

### Does inductor consume reactive power?

Now we can term that in one quarter cycle, the **inductor consumes the reactive power** and in the same quarter cycle the capacitor gives back the reactive power. Naturally, the inductor can be considered as consuming the reactive power from the power source and the capacitor give back (or produces) at the same time.

### What is the power of capacitor?

The energy equation implies that the energy stored in a capacitor **is always positive**. The capacitor absorbs power from a circuit when storing energy. The capacitor releases the stored energy when delivering energy to the circuit.

### Why does a capacitor consume 0 power?

In inductors and capacitors, the energy supplied by the source is stored in form of magnetic and electric energy respectively. The **energy supplied by source in one half cycle to the inductor or capacitor is fed back to source by the component in next half cycle**. So inductor or capacitor consume the net power zero.

### How is AC power calculated?

The average ac power is found by **multiplying the rms values of current and voltage**. Ohm's law for the rms ac is found by dividing the rms voltage by the impedance. In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance.

### What is the average power of a capacitor?

If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of **P=V2/R**, where V replaces the rms voltage.

### Is reactive power wasted?

The strength of the pull on the rope is the apparent power; only a portion of this power is “working” (real) power that pulls the railcar forward. Due to the angle of the horse's pull, **some of the energy expended is wasted as “non-working” (reactive) power**.

### Why does current lead in capacitor?

Leading current In circuits with primarily capacitive loads, **current leads the voltage**. This is true because current must first flow to the two plates of the capacitor, where charge is stored. Only after charge accumulates at the plates of a capacitor is a voltage difference established.

### What is the job of a capacitor?

A capacitor is an **electronic component that stores and releases electricity in a circuit**. It also passes alternating current without passing direct current. A capacitor is an indispensible part of electronic equipment and is thus almost invariably used in an electronic circuit.

### How are inductors and capacitors alike and different?

The power wave flow is opposite in direction as that of the inductor power flow so that it cancels the reactive power flow produced by the inductor. Now we can term that in one quarter cycle, the inductor consumes the reactive power and in the same quarter cycle the capacitor gives back the reactive power.

### Why does the inductor not consume the current?

In direct current, electrical resistance disrupts the current flow and consumes energy. However, the inductor interrupts the current flow but does not consume power. This is because the energy supplied from the power source is stored as the magnetic field’s energy in the inductor and then returned.

### How is energy stored in an inductor or capacitor?

In inductors and capacitors, the energy supplied by the source is stored in form of magnetic and electric energy respectively. The energy supplied by source in one half cycle to the inductor or capacitor is fed back to source by the component in next half cycle.

### What happens when capacitor and inductor are in steady state?

Under steady state condition, Inductor acts as a short circuit that means voltage across the inductor is 0V and capacitor acts as an open circuit that means current flowing through the capacitor is 0A. So, It is cleared that steady state power across an inductor and capacitor is 0.
