∙ 11y agoResidual current means even after the electric supply is cut, there remains some current in the component like coils etc. If you touch it, you will feel the shock depending upon the intensity of the residual current.
In some cases, it is highly dangerous. It needs to be removed by short circuiting the same or giving earth connection before touching them with open hands.

What is the residual voltage of a 380Vac 264KW generator?
Residual voltage is the vector sum of all three phase voltages. Ideally this will be zero.
How initially voltage build up in an alternator by residual magnetism?
The residual flux will help the phenomenon of changing flux. So that emf generation takes place.
How the doubly fed induction generator build up voltage?
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
For a 3 phase alternator why there is an AC voltage generated in the absence DC excitation?
due to residual magnetism
What is ripple voltage in 12 volt power supply?
A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
What is meant by residual voltage in a dc generator?
poles are partially magnetized this causes some voltage called residual voltage
What is the residual voltage of a 380Vac 264KW generator?
Residual voltage is the vector sum of all three phase voltages. Ideally this will be zero.
What is definition of residual voltage?
Net voltage in the Neutral of a three phase electrical system is called residual voltage.
What is residual voltage in lvdt?
Output voltage at the null position is ideally zero. But because of harmonics in the excitation voltage and stray capacitance coupling between primary and secondary usually some nonzero voltage exists at null voltage. This is called residual voltage. If it is less than 1 % of full scale output voltage ( which is the normal case) it is in the acceptable limits.
How initially voltage build up in an alternator by residual magnetism?
The residual flux will help the phenomenon of changing flux. So that emf generation takes place.
What is residual voltage for DC generator?
This case arises only in series dc generator current should be sent around the poles to magnetize. this current can the source(generator). current is passed through poles if it is loaded. but if it is not loaded current is zero through the field. load voltage should be zero actually.but this dont happen.we use generator frequently.due to this poles are partially magnetized this causes some voltage appear called residual voltageAnswerThere's no such thing as 'residual voltage'; you're confusing it with 'residual magnetism', which exists in the magnetic poles of a self-excited d.c. generator and which enables the build-up of its terminal voltage.
If a selfexcited generator has lost all of its residual magnetism can it build up an output voltage?
yes
How the doubly fed induction generator build up voltage?
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
For a 3 phase alternator why there is an AC voltage generated in the absence DC excitation?
due to residual magnetism

Why an input voltage exists for the motor started to move?
because of the residual magnetic flux that exists in the motor initially due to the poles
Why an input voltage exists for the motor just started to move?
because of the residual magnetic flux that exists in the motor initially due to the poles
