2  The decrease in the flow of charge.  Abbreviation: (R) OHM’s - Ω  Equation: R=V/I  Ex: What is the resistance if a device uses 1.5 V and 0.3 A of current? R=V/I R=1.5/0.3 5 Ω

3  An electromotive force or potential difference expressed in volts.  Abbreviation: (V) Volts  Equation: V=I*R  Ex: What is the electrical potential on a circuit if there are 10 Ω of resistance and a current of 5 A? V=I*R V=5*10 50 V

4  The rate at which charge flows past a point on a circuit.  Abbreviation: (I) Amperes - A  Equation: I=V/R  Ex: A Flashlight bulb has a resistance of 100Ω. What will the current be if it is put in a circuit with a 9V battery? I=V/R I= 9/ AMPs
