- 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.
