Resistors and Ohm's Law

See all sections

Solution: Two pieces of metal are shaped into resistors and are connected end-to-end. The first resistor, R1, has twice the length of the second resistor, R 2, but an equal diameter. If the resistors are made of the same material, and are connected to a voltage source, what is the ratio of the voltage across each resistor, V1 / V2 ?
