What is the phase angle difference between inductive load and resistive load?
Wiki User
∙ 11y ago
The phase angle is defined as the angle by which the load current leads or lags the supply voltage.
For a purely-resistive load, the phase angle is zero, because the load current is in phase with the supply voltage.
For a purely-inductive load, the phase angle is 90 degrees lagging.
But few loads are either purely-resistive or purely-inductive; typically, most loads are resistive-inductive. This means that, typically, the phase angle lies somewhere between zero and 90 degrees.

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 non-inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
How do you shift an ac phase?
It really does depend upon what you mean by 'shift'. For purely-resistive circuits, the load current is in phase with the supply voltage. For reactive circuits, the load current will lead or lag the supply voltage; for capacitive-resistive circuits, the load current leads, whereas for inductive-resistive circuit, the load current lags. You can change the angle by which the current leads or lags (the 'phase angle') by changing the amount of resistance or reactance.
In a highly inductive circuit if is small capacitance is added in series then the angle between v and you will be?
lagging
What is the phase angle between magnetic flux and voltage?
It depends on the starting phase, but it would be equal to the voltage.Resistive circuit don't change phase only inductive/capacitive circuits do. For a simple/ideal circuit the phase would be zero. In reality (with three phase power) it would be 0,120,-120 depending on which line your drawing power from and whether it is truly a pure resistive circuit.AnswerPhase angle is defined as the angle by which the load current leads or lags the supply voltage (not the other way around!). For a purely-resistive circuit, the load current is in phase with the supply voltage. For a resistive-inductive circuit, the load current lags the supply voltage by some angle. For a resistive-capacitive circuit, the load current leads the supply voltage by some angle.

What is the Difference between resistive and capacitive load?
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
In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
Why natural trend to lagging power factor?
Power factor is the cosine of an AC circuit's phase angle, where the expression phase angle is the angle by which a load current lags or leads the supply voltage.Lagging phase angles and power factors occur in resistive-inductive circuits. Leading phase angles and power factors occur in resistive-capacitive circuits.Most industrial and commercial loads are combinations of heating (resistive) loads and motor (inductive) loads -in other words, resistive-inductive loads. Accordingly, lagging power factors tend to be more common than leading power factors.
What is non inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
What is non-inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
Is converting ac to watts and dc to watts the same watts equals volts times amps?
Yes, watts is still volts times amps, for both ac and dc circuits. The complexity lies in the phase angle between voltage and current. If the circuit is purely resistive, the phase angle will be zero. If the circuit is capacitive or inductive, the the phase angle will vary, depending on frequency and on how much capacitive or inductive reactance there is. The difference comes into play when you consider true versus apparent power.
What is the phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
When is the power factor of a motor 1?
When the circuit is purely resistive or in resonance, i.e. capacitive and inductive reactance cancels out.Power factor is the ratio of apparent power over true power, and is the cosine of the phase angle between voltage and current.
How do you shift an ac phase?
It really does depend upon what you mean by 'shift'. For purely-resistive circuits, the load current is in phase with the supply voltage. For reactive circuits, the load current will lead or lag the supply voltage; for capacitive-resistive circuits, the load current leads, whereas for inductive-resistive circuit, the load current lags. You can change the angle by which the current leads or lags (the 'phase angle') by changing the amount of resistance or reactance.
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.
