Question

What are the Dependence of Resistance ?​

Answer 1

Answer:

Resistance depends on the geometry of a conductor as well as on what the conductor is made from, but it also depends on temperature (although we will often neglect this).

Answer 2

Resistance - It is a obstruction to the flow of charges.

• It is represented by 'R'
• SI unit - Ohm or Ω

$\large\begin{gathered} {\underline{\boxed{ \rm {\red{Dependence}}}}}\end{gathered}$

• Resistance of a wire is directly proportional to its length.

• Resistance of a wire is inversely proportional to the area of cross section of wire.

$\large\rm\purple{ \R \: ∝ \: \frac{1}{A} } \rm \:$

• Resistance depends on nature or material of wire.

• Resistance of wire depends on its temperature.

$\boxed{\sf\blue{ R_{T_2} \: = \: R_{T_1} \: \bigg( 1 \: + \: ∝ \: [ T_2 \: - \: T_1] \bigg)} \rm \:}$

Where ,

$\begin{cases}\bf\orange{ \diamond} \rm \: \: {T_1} \: = \: Temperature \\ \\ \bf\orange{ \diamond} \rm \:{T_2} \: = \: Temperature \\ \\ \bf\orange{ \diamond} \rm \:R_{T_2} \: = \: Resistance \: at \: temperature \: {T_2} \\ \\ \bf\orange{ \diamond} \rm \:R_{T_1} \: = \: Resistance \: at \: temperature \: {T_1} \\ \\ \bf\orange{ \diamond} \rm \:∝ \: = \: Temperature \: coefficient \end{cases}$
