An oscilloscope is used to monitor the current in a resistive wire. Compare the drift behavior and net displacement of the conduction electrons in the wire when it is connected to a direct current (d.c.) source versus when it is connected to an alternating current (a.c.) source.
Practise Edexcel GCSE Physics Charge, current and potential difference with exam-style questions for Foundation and Higher tier. 50 questions, matched to the Edexcel GCSE Physics (1PH0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
