What is mean drift velocity?Show answer
In metals is very large (around ), so the drift velocity is tiny, often a fraction of a millimetre per second, even though the electric field (and the lamp lighting) responds almost instantly.
What is q1?Show answer
State what is meant by an electric current. [1 mark]
What is q2?Show answer
A current of flows for . Find the charge that passes. [1 mark]
What is q3?Show answer
Explain, using , why current is the same at every point in a series circuit. [2 marks]
