Best Answer

The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.

What do you mean lagging in electrical?

Lagging means the current is out of phase, lagging behind, the voltage. This occurs when there is inductive reactance in the circuit, such as with motors and transformers.


What is the difference between current coil and voltage coil?

These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.


What determines leading or lagging power factor?

underdampedAnswerA lagging power factor describes a situation in which the load current is lagging the supply voltage. This describes an inductive load, such as a motor, etc.


What lagging or leading?

You must knew there's a sinusoidal wave form for both voltage nd current. That wave form is drawn between voltage/current nd phase angle. Unity: phase angle of voltage nd current matches, irrespective of magnitude leading: phase angle of current leads voltage by an angle lagging: phase angle of voltage leads current or current lags voltage by an angleAnswerThe terms, 'leading' and 'lagging' apply to a.c. loads. 'Leading' means that the load current leads the supply voltage, whereas 'lagging' means that the load current lags the supply voltage. 'Leading' currents occur in capacitive loads, whereas 'lagging' currents occur in inductive loads.'Leading' and 'lagging' refers to what the current is doing, relative to the voltage, never the other way around.


Why Power factor becomes less lagging when capacitor is switched on?

Because capacitor withdraw leading current from source and net resultant become less lagging.

Leading and lagging power factor?

The terms, 'leading' and 'lagging' refer to what the load current is doing, relative to the supply voltage (Phase difference) -never the other way around. If the current is leading the voltage, then the power factor is 'leading'; if the current is lagging the voltage, then the power factor is 'lagging'.

Would you compare generator current to line voltage to determine if your leading or lagging?

It's always the current that determines 'leading' or 'lagging' -i.e. the angle by which the current leads or lags the voltage.


Power factor lead or lag?

By definition, the terms 'leading' and 'lagging' refer to what the load current is doing with respect to the supply voltage. So, for a 'lagging power factor', it is the current that is lagging.

Why the current coil of wattmeter has more thikness wire than pressure coil?

Current coil carries the current.


What is current coil and voltage coil?

The current coil is one through which the current of source can pass. This coil is connected in series. The voltage coil is connected parallel to the applied voltage. In the current coil the quantity of current flowing is proportional to the current flowing in load while in the voltage coil, current flowing is proportional to applied supply voltage. The voltage coil current is independent of current flow in load. For a complete understanding, please refer to a watt meter diagram.

What is meant by lagging and leading circuit?

The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
