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