Question

What factors affect the resistance of a conductor?

Answer 1

Step-by-step explanation:

There are four factors affecting resistance which are

Temperature,

Length of wire,

Area of the cross-section of wire and

nature of the material.

Answer 2

Length, Area, Conductivity, Temperature

Step-by-step explanation:

The factors affection the resistance of a conductor are

(1) Length of the conductor (L): As the length (L) of the conductor increases, the Resistance(R) of the conductor also increase.

R ∝ L

(2) Cross sectional Area of the conductor(A): As the cross sectional area of the conductor(A) increases, the Resistance (R) of the of the conductor decreases.

R ∝1/A

(3) conductivity of the conductor(G): As the conductivity of the (G) of the conductor increases, the Resistance(R) of the conductor decreases.

R ∝ 1/G

(4) Temperature(T): As temperature(T) increases, the Resistance(R) of a conductor decreases.

T ∝ R
