Question

Resistance of a conductor is directly proportional to length.
True
False

Answer 1

True because Resistance = (resistivity x length)/ cross sectional area

Answer 2

Resistance is directly proportional to the length of the conductor.

Answer 3

that's right! @sludgey
\[\Large R = \rho \frac{L}{A}\]
where \rho is the resistivity of the material of our conductor,
L is the length of our conductor, and
A is the cross sectional area of our conductor
