These are not exactly lectures (its just a guy on youtube) but they cover the whole of Introduction to Electrodynamics book by Griffiths (which is an amazing book btw). If you want to learn about QED as well then his next book called Introduction to Elementary Particles covers a bit of QED calculations like scattering amplitudes, Feynman rules and cross sections etc.

Unfortunately I am not currently aware of any online resources for the later book.
