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 nature of power factor and its variation with firing angle when a single phase voltage controller feeds a resistive load?
With a pure resistive load the Power Factor should be 1.
What is the approximative power factor of an incandescent lamp?
Incandescent lamps are nearly pure resistive loads with a power factor of 1
What is a purely resistive circuit?
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
What does the measurement abbreviation RI stand for?
resistive index (RI) resistive index (RI)

Power factor for pure resistive circuit?
ratio between true power and apparent power is called the power factor for a circuit Power factor =true power/apparent power also we conclude PF=power dissipated / actual power in pure resistive circuit if total resistance is made zero power factor will be zero
How many watts in 1500VA?
Watts = Volts x Amps x Power Factor. To answer your question requires that the Power Factor be know. The Power Factor ranges from zero to one and is one for a pure resistive load. If your device is resistive the answer is 1500 watts.

What is an electrical load and how it can be measure?
Typically you are referring to a pure resistive load and not an inductive load. To measure a resistive load you need an Ohm meter. You can buy cheap ones for $10 to $20 on-line or at a store like Radio Shack. Usually they are combined with a volt meter.
Is computer is Resistive load?
It is resistive much load
Do air conditioners use resistive load or inductive load?
resistive loadAnswerIf the current is driving a motor, then the load is resistive-inductive.
What are the problems with switching AC currents in a circuit of pure resistance at unity power factor?
Power factor does not apply to a resistive circuit. Just the current will follow the voltage (in phase)
What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
Why does the resistor current stay the same when you adjust the power factor?
A pure resistive load always has a power factor of one. This is because the current and voltage waveforms are in phase in an AC circuit.
