Question

what happens to the resistance of a conductor as its length increases?
select one:
a. it increases
b. it decreases
c. it stays the same
d. it depends on the material

Explanation:

The resistance \( R \) of a conductor is given by the formula \( R=
ho\frac{l}{A} \), where \(
ho \) is resistivity (depends on material), \( l \) is length, and \( A \) is cross - sectional area. Assuming \(
ho \) and \( A \) are constant, as \( l \) (length) increases, \( R \) (resistance) will increase because resistance is directly proportional to the length of the conductor.

Answer:

a. It increases
