Why skin effect for a conductor is not applicable for DC?
As we know that skin effect occures in ac system.skin effect dependes on frequncy.In case of dc syastem frequncy is zero.So skin effect for conductor is not applicable for dc.
What is demagnetising effect of DC generator?
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
Why skin effect not act on the transformer?
Skin effect is a physical effect that operates on thick conductors. In a transformer the conductors are usually too thin for any substantial skin effect to occur.
Why skin effect is frequency dependent?
skin effect occures in ac system due to un uniform distribution of current in conductor.Ac system has frequency.SO we can say that skin effect is frequecy dependent.AnswerThe skin effect is caused partly by self inductance which will only occur with a varying current -i.e. with an a.c. current.
What is the effect of over loading in dc machine?
Heat, smoke, fire...
Why skin effect for a conductor is not applicable for DC?
As we know that skin effect occures in ac system.skin effect dependes on frequncy.In case of dc syastem frequncy is zero.So skin effect for conductor is not applicable for dc.
Skin effect related to ac and DC?
IT IS RELATED TO AC ONLY BKZ SKIN EFFECT DEPENDS FREQUENCY ONLY WHERE IS IN DC NO FREQUENCY
Why skin effect absent in dc system?
Skin effect is caused by the back emf produced by the self induced magnetic flux in a conductor. For a DC current, the rate of change of flus is zero, so there is no back emf due to changes in magnetic flux. Therefore, the current is uniformly distributed throughout the cross section of the conductor.
What is meant by skin effect?
The skin effect occurs in conductors carrying alternating currents, where the tendency is for the current to flow towards the surface of the conductor. The effect increases with frequency. At radio frequencies, the skin effect is so pronounced, that there is little point in using solid conductors, so tubes are used instead.The skin effect is responsible for the so-called 'AC resistance'. This is because the skin effect acts to reduce the effective cross-sectional area of a conductor, thus increasing its resistance compared to when a DC current passes through the conductor.
Can leprosy effect your skin?
yes. leprosy does effect your skin
What drugs skin side effect?
WHAT drugs effect our skin? It make our skin rough.
What is Skin effect in transmission lines?
when a conductor is carrying a steady DC current,it is uniformly distributed over the whole cross section of the conductor. however, an alternating current flowing through the conductor does not distribute uniformly . Rather it has a tendency to concentrate near the surface of the conductor. This is known as skin effect
What is demagnetising effect of DC generator?
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
What effect does it have on the skin menopause?
The effect of the skin menopause is that the skin wounds take longer to cure.
Why less loss occurs when you use DC supply than AC supply?
There are less loss occurs when we use DC supply than AC supply, because the frequency is zero in DC, so no Inductance & Capacitance exists.And there is no skin effect in the DC systems, so there is low resistance as compared to AC systems.Rac = 1.25*Rdcfrom Arun Kumar SRR
What is the difference between ac Hall effect and dc Hall effect?
The AC Hall effect is used to measure the sign and magnitude of an alternating magnetic field, whereas the DC Hall effect is used to measure the sign and magnitude of a steady magnetic field. In AC Hall effect, the magnetic field changes direction periodically, while in DC Hall effect, the magnetic field is constant.
Why skin effect not act on the transformer?
Skin effect is a physical effect that operates on thick conductors. In a transformer the conductors are usually too thin for any substantial skin effect to occur.
