A certain wire has a resistance R . The resistance of another wire identical with the first except having twice its diameter is

A cylindrical wire of length L and radius r has a resistance R. The resistance of another wire of the same material but half its length and half its radius will be:

A certain wire has a resistance R. What is the resistance of a second wire, made of the same material, that is twice as long and has twice the diameter?

A wire 50 cm long and 0.12mm diameter has a resistance of 4.0 Omega find the resistance of another wire of the same material whose length is 1.5m and diameter is 0.15 mm

The resistance of a conducting wire is R. Resistance of wire of twice the Iength and twice the diameter is

A wire has a resistance R . What wil will be its resistance if it is stretched to double its length?
