3. Use a wire of arbitrary length L. Measure its resistance across ends A and B, say R 1, using the metre bridge. Next, fold the wire so as to reduce its length to (L/2) and measure the new resistance, say R 2, across the ends A′ and B′. Finally, fold it again and repeat the observation for resistance across ends A′′ and B′′.
