Define the coulomb.
A charge of 60 × 10–6 C flows through a given section of a conductor in 140 × 10–3 s. Calculate the electric current, stating the final answer in mA.
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.
One equation for electric current states that
I = nAvq
Define the four terms used here to calculate current.
