  1. Q25.1 Two copper wires of different diameter are joined end-to-end, and a current flows in the wire combination. When electrons move from the larger-diameter wire into the smaller-diameter wire, 1. their drift speed increases 2. their drift speed decreases 3. their drift speed stays the same 4. not enough information given to decide
