Question

Two wires A and B are of equal length different cross sectional areas and madeof same metal
(a) (1) Name the property which is same for both the wires.
(ii) Name the property which is different for both the wires.
(b) If the resistance of wire A is four times the resistance of wire B
calculate
(1) the ratio of the cross sectional areas of the wires and
(ii) The ratio of the radii of the wire,
answer correct please for my exam​

Answer 1

Answer:

Explanation:

1) Resistivity will be same for both wires as the metal is not changing

2) Resistance will be different for both the wires

3) the rest of the subparts...do it yourself i am busy
