Q1:) Draw the shape of the curve obtained when a graph is plotted between I and V.

1) It is a straight line.

 

2) Resistivity of a conductor is a property of a material and temperature. It does not depend on geometry.

    Resistance is directly proportional to length and inversely proportional to cross-sectional area.

    Thus:

    a) The resistance is doubled.

    b) it is doubled

    c)  it is halved

    d)  there will be no change
