Do charges only flow along the surface of conductors as well?
What's the difference between EMF and voltage?
Is EMF referring to both voltage and current sources? Do any other types of EMF exist?
Doesn't a battery provide a current source since
and since
is constant for a battery and
is constant for a given circuit?
Why is current always equal across series resistors? Couldn't the speed of charges decrease due to the resistor?
Why do parallel resistors have the same voltage across them?
Which is the ideal voltage source, the battery symbol (parallel long and short line) or the battery symbol combined with the internal resistor?
What does an ideal current source look like physically?
What are the practical differences between a constant current and a constant voltage source? Why would you want one over the other?
Why does actual ground not always work as a ground?
