What else can I help you with?
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.

When an inductor tunes at 200 KHz with 624 pF capacitor and at 600 KHz with 60.4 pF capacitor then the self capacitance of the inductor would be?
around 10.05pf
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.
What is difference among resistor capacitor and inductor?
In an AC circuit through a resistor the voltage and current are said to be in phase. Ie on the oscilloscope in the sine wave as the voltage rises so does the current in tandem. Through an inductor an electromagnetic field is created in the coil which produces a back emf which acts against any change in voltage. This slows down any sharp change in voltage as when a circuit is energised. With an inductor the voltage and current are out of phase. The voltage is said to lead over the current. It is displaced by 90 degrees. It is ahead of the current by 90 degrees on the sine wave. Through a capacitor the current rises until it is fully charged and then no more current flows. An AC current is constantly changing direction at 50 Hz in the UK. Through a capacitor the current leads over the voltage by 90 degrees in the sine wave. A capacitor can balance out the effect of the inductor. The inductor decreases the power factor, the capacitor increases the power factor. With an inductor a circuit draws more current, with a capacitor the current draw decreases. P=IxVxPf. Where Pf is the power factor or power correction factor. Factories will have a big capacitor to correct the power factor for induction motors. This improves the electrical efficiency and lowers the electric bill!
