Introducing the polarisation vector in dielectric materials and understanding the relationship between polarisation and surface charge density.
About me: I studied Physics at the University of Cambridge, then stayed on to get a PhD in Astronomy. During my PhD, I also spent four years teaching Physics undergraduates at the university. Now, I'm working as a private tutor, teaching Physics & Maths up to A Level standard.

I do always enjoy revisiting these things and making sure I can still derive the important equations!
