Today we learned about circuits and currents.
We learned the difference between an alternating current and direct current which is self explanitory by the name
We learned what a current was, the flow of electric charge, and that the symbol was I. The unit of charge is an Ampere or Amp.
Resistance is the opposition to current flow and is represented by the symbol R. Its unit is the Ohm.
Ohm's Law-At constant temperature, the current in a metallic conductor is directly proportional to the potential difference between its ends.
Ohm's law has a few equations such as R=V/I, I=V/R, and V=IR

the pictures really helped me review for the test.
