Question:
A length of copper wire is joined in series to a length of silver wire of the same diameter. Both wires have a current in them when connected to a battery. Explain how the mean drift velocity of the electrons will change as they travel from the copper into the silver. Electron number densities:
Copper n = 8.5 × 1028 m−3
Silver n = 5.9 × 1028 m−3.
