Why pure inductive load is used to for finding zero power factor instead of using pure inductive load?
The question makes no sense. It asks why a pure inductive load is used ... instead of a pure inductive load. Please restate the question.
Why is there a difference in current in a coil when you apply dc voltage and then AC voltage to it?
A coil has both resistance and inductance. When you apply a d.c. voltage, the opposition to current is the resistance of the coil. When you apply an a.c. voltage, the opposition to current is impedance -the vector-sum of the coil's resistance and its inductive reactance. Inductive reactance is proportional to the inductance of the coil and the frequency of the supply.
What is the inductive reactance of a 5 Henry coil connected to a 60 hz source?
inductive reactance= XL= 2*pi*.1*60=12pi ohm
Are solenoid valves resistive loads or inductive loads?
Resistive Load An electrical load which is characteristic of not having any significant inrush current. When a resistive load is energised, the current rises instantly to it's steady-state value, without first rising to a higher value. An electrical load in which voltage and current are converted to energy in the form of heat; i.e., an electrical heater, incandescent bulb. Inductive Load An electrical load which pulls a large amount of current (an inrush current) when first energized. After a few cycles or seconds the current "settles down" to the full-load running current. The time required for the curren to "settle down" depends on the frequency or/and the inductance value of the Inductive load
What is Pure Resistive?
A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.

What is the motto of Inductive automation?
Inductive automation's motto is 'Breakthrough to Possible'.

What is ideal choke coil?
An ideal choke coil has only inductance. It has zero resistance and no stray capacitance, therefore no resonances.
What factors affect the inductive reactance of a coil in a A C circuit?
Current Flow I believe.

inductive reactance= XL= 2*pi*.1*60=12pi ohm
What is purpose of diode in solenoid?
If the coil is powered with DC voltage, an inductive voltage is created anytime power to the coil is de-energized. The inductive voltage is called an inductive kick and it is up to ten times the applied voltage and is in reverse polarity to the applied voltage. A diode or other type of suppression device must be connected across the coil of the solenoid to protect any other electronic components in the circuit that may be damaged by this voltage. The diode is connected in reverse bias across the DC solenoid coil so that when voltage is applied in normal polarity, the diode does not provide a path for current. When the solenoid coil is de-energized, the inductive voltage is the opposite polarity to the power supply, so it will flow through the diode and back into the coil. Since the coil is made of a large length of wire. the energy of the inductive voltage will be dissipated as it moves through the wire. This will render the excessive inductive voltage harmless. The fact that the inductive voltage will travel through the diode in the forward bias direction means the 0.7-1 volt drop across the diode junction will also limit the V=< (dv/dt) surge. Fig. 4 (below) illustrates an example of the diode connected across the coil of a solenoid that is powered with DC voltage.
What is the difference between inductive and non inductive resistor?
INDUCTIVE RESISTOR:Any circuit in which change in current is accompained by change in flux and therefore by inuced emf is said to be inductive. NON-INDUCTIVE:if a double wire is wound arround an insulating rod,the emf can not be induced because the wire is doubled back on itself at its centre and the doubled wire is wound arround an insulator.thus every turn of the coil has adjascnt turn which is carring current in opposite direction.the magnetic field generated by each other cancel out each other effect.hence no emf is induced in coil and coil has zero inductance.
What is the symbol for pure silk?
An "s" with coil around it
What is phase between voltage and current in a pure inductive circuit?
The phase angle between voltage and current in a purely inductive circuit, under ideal circumstances where there is no resistance at all, is 90 degrees.
