Current - -Rate of flow of charge
Resistance - -The ratio of a components
potential difference to its current
Coulomb - -The amount of charge passing
a point when a current of 1A flows for 1s

component when 1 joule of energy is used to
Potential difference - -The work done per move a coulomb of charge through a component
unit charge in moving a small point positive
charge between two points
Ohm's Law - -Provided that the physical
conditions remain the same, the current through
Threshold Voltage for a Diode - -The an ohmic conductor is directly proportional to the
voltage at which a current will begin to flow at, potential difference across it
assumed to be +0.6V if not stated
Ohmic conductor - -A material that follows
Reverse Bias - -When very little currency Ohm's law when physical components remain the
can flow in the reverse direction of a diode same
Variable Resistor - -Can be used to Diodes - -Components made from semi
change the current through a circuit can also be conductors that only allow current to flow in one
called a rheostat direction
NTC Thermistor - -(A type of Resistivity - -The resistance of a 1m length
semiconductor) that has decreasing resistance of wire with a 1m^2 cross sectional area
when its temperature increases - negative
temperature coefficient
Superconductor - -A material that has zero
resistivity when it is cooled below its critical
Transitional Temperature - -The critical temperature
temperature at and below which a
superconductor has zero resistivity
Critical Temperature - -The temperature
below which a material will have zero resistance
Semiconductor - -A group of materials and will become a superconductor
which conduct electricity (not as well as metals),
when their temperature rises they can release
more charge carriers and their resistance Power - -The rate of transfer of energy
decreases
