Capacitors and Inductors theoretically consume no power. In real life, they only consume power because they have an internal resistance.

How do you find whether it is inductor or capacitor if only power factor is given?

in case of inductor or capacitor power factor is always zero.as power factor is cosine of phase angle between voltage and current. in case of inductor and capacitor phase angle between voltage and current is 90 so it become zero so if given power factor is zero then it can be inductor or capacitor.

Explain the function of the capacitor and inductor in a power supply?

A capacitor resists a change in voltage (dv/dt = i/c). An inductor resists a change in current (dl/dt = vl). Together, a capacitor and inductor make a tuned circuit. Usually, in a linear power supply, there is a capacitor in parallel with an inductor in series, and often, in a pi filter, another capacitor in parallel. This reduces the peak to peak voltage at the output. It is also possible to put an inductor in series with the rectifier diode, as as to reduce inrush current. In a switching power supply, things are a little bit different. The primary inductor is a current pump, maintaining constant current flow to the load, controlled by the pulse-width oscillator which switches between on-current from source and off-current from schottky diode. The capacitor in this case filters the output, so as to reduce high frequency harmonics.


Why inductor use in series capacitor in parallel?

That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.

What happens if you put a inductor instead of the capacitor at the capacitor start motor?

An inductor can be used, in principle, but it has to be the right inductance, it will waste more power than a capacitor, and the motor would rotate the opposite way.

Why you use capacitors in power supply?

You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.

Where is energy stored in a capacitor and in inductor?

Energy is stored in a capacitor in the electric field between its plates. In an inductor, energy is stored in the magnetic field around the coil.

Why we need output capacitor in buck converter?

I've been looking at them for a bit wondering the same question. I believe: When the switch is closed, the inductor will have a high resistance, limiting power directly from the main power source. During this time, the capacitor will be delivering voltage to the output. When the switch is open, the inductor will power the output while recharging the capacitor. From what i get it's not *necessary*, but does even out the voltage considerably. Maybe someone has a better answer...


How does led behave when connected in a circuit with capacitor and inductor in series when the switch is closed for 5 minutes?

In principle, the LED would blink some number of times after the switch is closed, then go dark and stay dark. The rate of blinking depends entirely on the value of the capacitor and inductor, and the length of time it persists depends on the resistance of the inductor and the power dissipated by the LED. I don't think it would be possible to find a capacitor and inductor with large enough values that the blinks would be perceptible to the eye, and an inductor and LED with power dissipation small enough that the blinks would persist for five minutes before the LED goes dark.
