Question

Factors affecting Resistance & How they affect

​

Answer 1

$\huge{\underline{\mathtt{\red{❥A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

Resistance is:

• directly proportional to the length of the conductor.

• directly proportional to nature of the conductor.

• directly proportional to the temperature of the conductor.

• inversely proportional to the cross-sectional area of the conductor.

Answer 2

Answer:

here is ur ans:-

Resistance decreases with an increase in temperature. The thermistor is a temperature-dependent resistor and its resistance decreases as temperature rises. The thermistor is used in a circuit that senses temperature change. There are four factors on which resistance depends.

(1)Length(L)

(2)it’s cross-sectional area(A)

(3)the type of material

(4)nature of material
