Q

How does the direction of current relate to the direction of electron flow

A
  • electrons flow from a point of lower electric potential energy to a point of higher electric potential energy
  • > because we are talking about a negative charge here
  • current flows from a point of higher electric potential energy to a point of lower electric potential energy
  • > because we are talking about a positive charge here

Q

What is electromotive force? Is it actually a force?

A
  • it is when no charge is moving between the two terminals of a cell that are at different potential values
  • > the voltage is referred to as the electromotive force
  • > it isn’t actually a force

-it is the energy require to result in a current
