why heat produced at junction of two different conductor.
what care should be taken to minimize it.
Answer Posted / dolphin
generally different conductors are having different
electron density.if current flows from high
electron density conductor to low density conductor
heat will be produced at the junction due to sudden
change in electron density.to avoid this the two
conductors to be junctioned should have minimum
difference in electron density.in some other cases
contact resistance causes heat if they are not
tightly held together.
