Question

Does copper have a high resistance?

Answer 1

Explanation:

The copper does not have a high resistance such as:

1. Copper has the highest electrical conductivity rating of all non-precious metals.
2. Its atoms vibrate less, and so they impede the flow of electrons less.
3. Mathematically express as:

$\sigma =\frac{1}{\rho }$

Where $\sigma$ is the conductivity of the conductor and $\rho$ is the resistivity of the conductor.

$\mathrm{\sigma }=\frac{\mathrm{l}}{\mathrm{RA}}$ $\left[\because \mathrm{\rho }=\frac{\mathrm{RA}}{\mathrm{l}}\right]$

Where $\mathrm{R}$ is the resistance of the conductor, $\mathrm{A}$ area of the cross-section, and $l$ length of the conductor.

Since conductivity is inversely proportional to the resistance of the conductor

Therefore, from the above point conclude that the conductivity of copper is very high which means that the copper has a very low resistance.

Hence, copper does not have high resistance.
