You would find exactly what you need from most good undergrad
textbook on physics.

My prefered ref is "Physics II" by Halliday & Resnick. They expond
on what you are looking for rather clearly, but there are others. I have
heard good vibes about "Intro. to Electrodynamics" from Griffiths.

One of the possible ultimate sources in my view is "Electromagnetic Theory"
by Julius Adams Stratton,
