| Potential Difference (V) | a measure of the potential energy due to the separation of charges (Volts). |
| Capacitance (C) | the ratio of the amount of charge stored on the plates (Q) and the potential difference (V) across the plates (Farads). |
| Current (I) | the movement of positive charges per unit of time (Amperes). |
| Conductance (g) | indicates the capacity of an object to transmit a current (Siemens). |
| Resistance (R) | the reciprocal of conductance. |
| Capacitor | two conducting plates separated by an insulating layer and can store charges of opposite sign. |
| Battery (E) | drives a current around a closed circuit from its positive to its negative terminal. |
| Ohm's Law | V = IR |
| Voltage Divider | a series combination of conductors. |
| Farad (F) | the unit of measurement for capacitance. |
| Ampere (A) | the unit of measurement for current. |
| Siemen (S) | the unit of measurement for conductance. |
| Volt (V) | the unit of measurement for potential difference; indicates work done (J) to move a charge (C) between two points. |
