Question

why the connections between the resistors in a metre bridge are made of thick copper strips ?​

Answer 1

Explanation:

The connections between the resistors in a meter bridge are made of thick copper strips because the resistivity of the copper wire is very low. As, the connections are thick, so the area become very large and the resistance of eh wires become almost negligible..

hope this will help you.

Answer 2

$\huge\mathfrak{Answer}$

Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.

Materials that conduct electrical current easily are called conductors and have a low resistivity. Those that do not conduct electricity easily are called insulators and these materials have a high resistivity.
