If the diameter of the conductor is increased

A. the inductance is increased
B. the inductance is decreased
C. the resistance is increased
D. no change in inductance and resistance

Answer: B. the inductance is decreased

Explanation:

Resistance R = ρl/a

Where,

ρ = Resistivity

l = Length of the conductor

a = area of the conductor

If the diameter of the conductor is increased, area will increase and resistance is decreased.

If the diameter of the conductor is increased, radius will increase and inductance is decreased.
