Topic explainers for Edexcel IAL Physics Unit 4 (WPH14). Covers circular motion, gravitational and electric fields, capacitors, electromagnetic effects, momentum, impulse and further mechanics. Watch these alongside or before the past papers.
Curated by: Doctor No Does Science (16 videos)
In this video we explore capacitors in depth, covering electric field, potential, and capacitance. We work through the charging and discharging processes, analysing charge, voltage, and current curves alongside their logarithmic plots. We cover the time constant, the 37 percent rule for discharging, and the 63 percent rule for charging. We also look at capacitors in series and parallel and work through the underlying mathematical derivations. This video covers Topic 6B Capacitors from the Edexcel International A-Level Physics specification, including Capacitor Basics, Charging and Discharging, and Capacitor Mathematics.
