Use words from the list below to complete the description of the movement of charge carriers in a conductor.
average current
delocalised
electric force
electric field
randomly
drift
The charge carriers in a metal conductor are _____ electrons.
Normally the electrons move _____ in all directions, but if a potential difference is applied between two points on the conductor, then an _____ is created.
This causes an _____ to act on on the charge carriers, causing them to _____ along the conductor in a resultant direction.
Therefore we can say that a steady _____ flows through the conductor.
A current of 3.0 A flows in a copper wire of cross-sectional area 1.5 × 10−6 m2. Assume that the charge carriers are delocalised electrons with a charge of −1.6 × 10−19 C, moving with an average drift velocity of 1.0 × 10−4 ms−1.
