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