| electrons are attracted to _______ charges | Positive |
| electrons come out of the _______ terminal | Negative |
| electrons move through the wire toward the _______ charge and away from the _______ charge | Positive, Negative |
| holds an electrical potential | Power Source |
| an example of a power source | Battery |
| the relationship between the electrical potential and the resistance offered by the battery and the wire | Ohm's Law |
| the equation for Ohm's Law | V=IR |
| character that represents electric potential | V |
| character that represents positive current measured in dq/dt | I |
| character that represents resistance measured in Ohms | R |

| represents the potential in volts | V |
| represents the current | I |
| the rate of positive charge transferred per unit time | Current |
