Lesson: Electric Current Physics

Students will be able to

• recall that electric charge is measured in coulombs,
• recall that electric current is measured in amperes (A),
• understand that electric current is the flow of electric charge,
• understand that in a typical electric circuit, current is the flow of negatively charged electrons along the wires,
• understand that the negatively charged electrons do move, but the positively charged nuclei do not,
• understand that conventional current is in the opposite direction to the movement of electrons and that this is because historically it was thought that the positive charges were moving, but this was later proven to be incorrect,
• use in all permutations.
