The Resistance of a Wire Varies Directly with Its Length

question 82

Short Answer

The resistance of a wire varies directly with its length and inversely with the square of its diameter. If 100 feet of wire with diameter 0.04 inch has a resistance of 30 ohms, what is the resistance of 50 feet of the same type of wire if its diameter is 0.08 inch?
