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