AQA A LEVEL PHYSICS Exam Questions
and Answers 100% Solved
Electromotive force (emf) - ✔✔Amount of electrical energy produced by a
battery/source per 1C of charge
Power - ✔✔Rate of transfer of electrical energy to a component per second
Resistance - ✔✔Potential difference divided by the current, if the electrical
energy used when a current of 1 Amp moves through a component
Electrical current - ✔✔1A of current is defined as 1C of charge passing a
point per second
Potential difference - ✔✔Amount of electrical energy converted or
transferred per 1 C of charge between 2 points
Ohm's law - ✔✔The current passing through a conductor is directly
proportional to the voltage as long as the physical conditions don't change
Resistivity - ✔✔The resistance of a 1m^2 cross section conductor with a
length of 1m

Critical temperature - ✔✔The temperature that below which a
superconductor has no resistance and very large currents can pass
through with very small voltage/very small energy losses
Internal resistance - ✔✔An electrical source or cell's opposition to the flow
of charge through it, defined as the loss of pd per 1A current when a
current passes through the source/cell
Isotopes - ✔✔Nuclei with the name number of protons but different number
of neutrons
Pair production - ✔✔When a particle and its corresponding anti-particle are
produced from a photon with energy greater than the total rest energy of
the 2 particles
Annihilation - ✔✔When a particle and its corresponding anti-particle collide
they annihilate converted their kinetic energy and rest energies into 2 high
energy photons(E=hf)
Moment - ✔✔Force multiplied by perpendicular distance between force and
the pivot
