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
For a purely-resistive circuit, the load current is in phase with the supply voltage, so its phase-angle is zero. Since power factor is the cosine of the phase angle, the power factor must be unity (1).
In AC circuit, a pure resistive load doesn't shift phase the current, so its power factor is 1.
The power factor of a resistive load is 1.i need the circuit
Power factor does not apply to a resistive circuit. Just the current will follow the voltage (in phase)
In a pure resistive circuit the voltage and current are in phase. In an inductive circuit they are fro zero to 180 degrees out of phase. If they are in phase the Power Factor is 1 and 180 degrees the PF is zero. The exact amount of the phase difference depends on the specific circuit.
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
Power Factor is a maximum of one when the voltage and current in an AC waveform are in phase. Since power in watts is equal to voltage x current x power factor, you get maximum wattage with power factor = 1. This occurs with a pure resistive load. When you power an inductive load like a motor the power factor decreases and so does the delivered power. That is why motors are typically rated in VA, or volt-amperes rather than watts. So y Ou can assume power factor = 1 when you have a load measured in watts like a light bulb or space heater and perhaps in the .75 range for an inefficient motor.
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load
Power factor does not apply to a resistive circuit. Just the current will follow the voltage (in phase)
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.
With a pure resistive load the Power Factor should be 1.
Incandescent lamps are nearly pure resistive loads with a power factor of 1
In a pure resistive circuit the voltage and current are in phase. In an inductive circuit they are fro zero to 180 degrees out of phase. If they are in phase the Power Factor is 1 and 180 degrees the PF is zero. The exact amount of the phase difference depends on the specific circuit.
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.
Volts = current (In amps) x Resistance (In ohms) Watts = Volts x Current x PowerFactor Power Factor = 1 in a pure resistive circuit
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
If a furnace has a power factor not equal to 1 then there is a motor involved. If it was pure resistive element the Power Factor would be 1. That being said the motor can operate at .2 PF, but this is unusual and not very efficient. If this is the case I would expect that you have a bad motor control circuit and there may be a blown capacitor.
Watts = Volts x Amps x Power Factor To make your calculation you need to plug-in the Voltage and Power factor. The Power Factor is a value from zero to one with one being a pure resistive load.
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
