Answer / iamdon
A fuse is an electrical conductor whose melting point is
low.It is always connected in series with the apparatus
whom we wish to protect under the condition of short
circuit or such faults which causes a heavy current flowing
through the appratus that can damage the appartus.Under the
heavy current flow, the fuse element burn itself and
disconnect the appratus from line and protect it from
burning.

Answer / desingurajan ramco cements...
Fuse not having low melting point..... it is always having small thickness when compare to wherever it is connecting in the conductor.... CURRENT MEANS FLOW OF ELECTRONS...... when any faults occurs (like, short circuit..etc) more electrons flow through the fuse compare to normal running condition. that time more electrons not able to flow through the small area(ie fuse). at the time fuse will be over heated. and it will melt. and proper fuse wire having aprox 800C. melting speed is based upon the fault level......

What is the function of a capaitor in 1-phase IM?
In alternator generally we give DC voltage to field of alternator but field (excitor)produce Ac & converts into DC by rotating rectifier(RR ) then fed to rotor .my question is why we cannot give dc voltage directly to rotor instead of Excitor & RR ?
