what does the resistance tell us
the potential difference required to drive a current through a component / or how much energy is required to push a coulomb of charge through
what is the unit for resistance
ohms
at a constant temperature, describe the relationship between current and potential difference through a ohmic conductor
The current through an ohmic conductor (at a constant temperature) is directly proportional to the potential difference across the resistor. This means that the resistance remains constant as the current changes. This means graph will show a straight line passing through zero
what is an ohmic conductor
A conductor that obeys Ohm's Law i
in a filament lamp, what happens to filament wire when electrical current passes through
get extremely hot
