Word Definition
Current (Ampere) [11] ‘Rate of flow of electric charge.’
Potential difference (Volt) [12] ‘Difference in the amount of energy that charge
carriers have between two separate points in a
circuit.’
Electrical charge (Columb) [13] Physical property of matter that experiences a
force when place sin an electromagnetic field.
Resistance (Ohm) [14] ‘A measure of the opposition to current slow in
an electrical circuit.’
Conductance (Siemen) [15] A property of a component that describes how
the electric current in the component relates to
the electrical potential difference across it.
Electrical Power (Watt) [16] ‘The rate at which electrical energy is
transferred by an electric circuit.’
Capacitance (Farad and sub-units) [17] The ability a system has, to collect and store
energy in the form of an electrical charge.
