An inductor is a device which stores energy as a magnetic energy.... Ideal inductor have no resistance.....so there is no power loss.... power loss = (I*I)*R

Power factor is least in capacitance or resistance or inductance?
inductance
What is a pure capacitor?
whose resistance=0,inductance=0
Which conditions exist in a circuit of pure inductance?
super conductivity
Why do you need capacitor during copper loss measurement of Transformers?
The copper loss measurement must be replaced by load loss measurement in accordance to IEEE C57.12.00 and C57.12.90. Since that a power transformer is conected typically with one winding short circuited and the rated current is supplied in the other (typically high voltage side), the transformer is like an almost pure inductance load, with a lag power factor between 0.01 and 0.03. Therefore a capacitive reactive power is required to compensate this almost pure inductive reactive power demanded by the test. If you require further information please let me know.
Is inductive reactance considered when calculating power loss in AC cables?
No, because it is not loss - inductance by definition will cause reactive power which can be compensated for using capacitor banks (one example). I^2 * R losses (power loss through the cable) takes into account the resistance of the line.
What is the Relationship between power factor and current?
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
In a pure inductance circuit the current lags the voltage by what degree?
90 degrees
What is Power that is applied to an entire circuit consisting of resistance capacitance and inductance is called?
The unit of power measured is watt, irrespective of resistance, capacitance or inductance of the circuit.
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.
What are the effects of reactive power?
inductance and capictances, lowpower factor
What does LT stand for in power transformer?
Transformer Inductance?
Why current lagging in the coil?
The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.
