Two copper wires that are equal in length but have different diameters carry the same current. Which statement correctly describes the movement of charged particles through the wires?
- ACharged particles are provided by the power supply. Therefore the speed at which they travel depends only on the voltage of the supply.
- BThe charged particles in both wires move with the same average speed because the current in both wires is the same.
- CThe charged particles move faster through the wire with the larger diameter because there is a greater volume through which to flow.
- DThe charged particles move faster through the wire with the smaller diameter because it has a larger potential difference applied to it.
