Question

find observation of to find the resistance of a given wire using metre bridge and hence determine the specific resistance of its material​

Answer 1

Answer:

Record the observations in a tabular form. Stretch the resistance wire to find its length using a metre scale. Using screw gauge measure the diameter of the wire at four different places keeping it in a mutually perpendicular direction. Record the observations in the table.

Explanation:

Cut the resistance wire at the points where it leaves the terminals, stretch it and find its length by using a metre scale. Measure the diameter of the wire at least at four places, in two mutually perpendicular directions at each place with the help of screw gauge. Record your observations as given in tables.
