==Key Stage 4==
===Meaning===
'''Ohm's Law''' states that "The [[Electrical Current|current]] through a [[Electrical Resistor|resistor]] at constant [[temperature]] is [[Directly Proportional|directly proportional]] to the [[Potential Difference|potential difference]] across the [[resistor]].
===About Ohm's Law===
: '''Ohm's Law''' only applies to [[Electrical Conductor|conductors]] at a constant [[temperature]].
: '''Ohm's Law''' only works at low [[Electrical Current|current]] because [[Electrical Current|current]] has a [[heating]] effect on a [[Electrical Conductor|conductor]].
: An ideal [[resistor]] follows '''Ohm's Law'''.
