A wire has variable cross-sectional area. The cross-sectional area at Y is double that at X. At X

Описание: A wire has variable cross-sectional area. The cross-sectional area at Y is double that at X. At X, the current in the wire is I and the electron drift speed is v. What is the current and the electron drift speed at Y

This question is about the usage of concepts from the chapter ELECTRICITY, - current flow, drift velocity, cross section of the conductor, cross sectional area, electron density, charge density, to answer this MCQ. This question is taken from IBDP Paper-1, TZ2 PHYSICS SL 2017 MAY. EXAM. To see all the MCQs for this exam and also for other exams or past papers, visit: https://rathankar.com Links
