''NB: You only need to know what happens with identical [[resistors]] in [[Parallel Circuit|parallel]].'' : When identical [[resistor]]s are added in [[Parallel Circuit|parallel]] there are more paths for the [[electricity]] so the [[Electrical Resistance|resistance]] is reduced. {| class="wikitable"|-|[[File:ResistorsParallel2.png|center|200px]]|[[File:ResistorsParallel3.png|center|200px]]|[[File:ResistorsParallel4.png|center|200px]] |-| style="height:20px; width:200px; text-align:center;" |Two identical [[resistor]]s in [[Parallel|Parallel circuit]] gives twice the number of paths, so has half the [[Electrical Resistance|resistance]]. The [[Electrical Resistance|resistance]] between points A and B is 12Ω.| style="height:20px; width:200px; text-align:center;" |Three identical [[resistor]]s in [[Parallel|Parallel circuit]] gives three times the number of paths, so has a third of the [[Electrical Resistance|resistance]]. The [[Electrical Resistance|resistance]] between points A and B is 8Ω.| style="height:20px; width:200px; text-align:center;" |Four identical [[resistor]]s in [[Parallel|Parallel circuit]] gives four times the number of paths, so has a quarter of the [[Electrical Resistance|resistance]]. The [[Electrical Resistance|resistance]] between points A and B is 6Ω.|}
