Question

Is directly proportional to the length and resistivity of the conductor.

Answer 1

Answer:

B) resistance

Explanation:

the resistance of a wire is proportional to its length, and inversely proportional to its cross-sectional area.

Answer 2

The resistance of conductor is directly proportional to length and resistivity.

Answer: Option B

Explanation:

Resistance is present in an electrical object or rather introduced to counter check the flow of the current. It is similar to the mechanical friction in the conceptualization of its existence and effect.  

It is directly proportional to the length of the electric circuit. It is being measured and noted in ohm. The formula for resistance is –

                              $R=\rho \frac{l}{A}$

Where,

R - the Resistance of the wire,  

$\rho$ - the resistivity of the wire  

L - The length of the wire

A - the area of cross section of the wire
