Question

define resistance and fuse wire.....
plz answer

Answer 1

Resistance= Resistivity * length /Area of cross section....

Answer 2

RESISTANCE--

1)-The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor.

2)-The inverse quantity is electrical conductance, and is the ease with which an electric current passes.

3)-Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). 

FUSE--

1)-A fuse is a safety device in an electric plug or circuit. It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. 

2)-Wiring regulations usually define a maximum fuse current rating for particular circuits.

3)-When an electric device fuses or when you fuse it, it stops working because of a fault.
