Detailed Solution

The above statement is True.
"The opposition experienced by the current flowing through the circuit is known as the resistance."
In addition, the material's resistivity can be defined as "the property by which the material opposes the flow of the current through it." Three variables affect a conductor's resistance. The conductor's length, cross-sectional area, and material resistivity are these elements. Also, the material's resistance is directly proportional to the conductor’s length and the material's resistivity. It is inversely proportional to the cross-sectional area of the conductor. Mathematically, it can be written as

R = ρ \frac{l}{A}

Where

ρ

is the resistivity of the material,

l

is the length of the conductor, and

A

is the cross-sectional area.
