AQA A level Physics Paper 1 Examquestions with Answers
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
