Answer / sunil

ans is 1- high resistance & low temp

Answer / shubham

high resistance and low melting point material must be used
as fuse because, a fuse (from the Latin "fusus" meaning to
melt) is a type of "sacrificial over-current" protection
device. Its essential component is a metal wire or strip
that melts when too much current flows, which interrupts the
circuit in which it is connected.
So as high current/ over-current flows through the fuse due
to high resistance high (I^2*R)power loss will take place
thus generating heat in the wire and the wire will melt
quickly as its melting point is low
Material used in fuse wire
Fuse wire is a thin wire made of different types of alloys
of chromium, aluminum, iron, nickel etc. The fuse wire
alloys are:
* Aluchrom alloy
* Cronifer alloy

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
