Hey all. I am taking my second college physics course (electromagnetic physics) and am looking for some help deriving the equations. I found it very helpful to know how to derive many of the equations in my first physics course. So far we have studied e fields, guass's law, capacitors, resisters, potential, and power. The equations are begining to pile up. My professor said they can all be derived from Va-Vb=∫E ds Is he accurate?
