What is ideal choke coil?
An ideal choke coil has only inductance. It has zero resistance and no stray capacitance, therefore no resonances.
What is the reciprocal of the power factor?
impedance/resistance
What are the parameters of choke coil?
inductance and resistance are the parameters of the choke cil
What are design equations of a choke coil?
nebonda
What are the applications of choke coil?
choke coils are various depend upon the specifications it built....for example if u take 0-5 amp choke coil it is used in household applications like for florescent lamps....
What is quality factor for choke coil?
the quality factor for choke coil is impedence divided by resistance in a given circuit

How to calculate power consumption by induction melting furnace?
simply by measuring the coil voltage, coil current & power factor.
What are the parameters of choke coil?
inductance and resistance are the parameters of the choke cil
How is the power factor of an Electrodynamometer type wattmeter improved?
Power Factor of an electrodynamometer can be improved by connecting a large resistor in series with the current coil.
Why in coil power factor is low?
A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.

Advantage of a choke coil over a resistor in a power supply filter?
A choke is an inductor. For typical power frequency, an inductor will slightly change the power factor, but will not actively use much energy. An abnormal voltage spike on a power supply is equivalent to voltage at a much higher frequency. Inductors appear to be a much greater impedance to high frequencies. This allows the choke to pass "normal" power, while at the same time it blocks "abnormal" power.A resistor acts independent of frequency. It will limit the effects of the high frequency voltage spikes by dissipating their energy, but it will do the same for the normal power system frequency. In effect, it is always using power, when the choke only uses what you don't want to get to the power supply.

What is Single phase choke coil?
A single-phase choke coil is an inductor that is used in single-phase power applications to filter or block high-frequency noise or harmonics from entering a system. It can also be used to limit the amount of current flowing in a circuit. The choke coil is typically made of a coil of wire wound around a magnetic core.
What is choke coil?
A choke coil is an inductor, which is designed to block a particular frequency in an electrical circuit while passing signals of very less frequency or direct current.
