Question

plz answer these questions

Answer 1

1)On the amount of conduction possible in the conductors.

Answer 2

1 ..resistance depends upon
Length of conductor is directly proportional to resistance.
Area of conductor is inversely proportional to resistance
Temperature is directly proportional to resistance
Nature of material of conductor
2...current will flow more easily through thick wire because since it has more area so resistance will be less.
4..coils are made of alloy because
Alloy has high resistivity so more heat is produced
It doesn't undergo oxidation even at high temp
5 b silver
5 a iron is a good conductor since it has low resistivity as compared to mercury
