Question
electric current quiz complete which two wire properties would provide the greatest resistance to the flow of a current? short, thin long, thin hot, thick cool, thick
Resistance of a wire depends on length, cross-sectional area (thickness), and temperature. Longer wires have more collisions for electrons, increasing resistance. Thinner wires (smaller cross-sectional area) reduce electron flow paths, increasing resistance. Hotter wires have higher resistance as atoms vibrate more, impeding electrons. So long and thin wires maximize resistance.
