the longest math sentence ever...Thus, the resistance of a parallel circuit is equal to the reciprocal of the sum of the reciprocals of the resistances of the individual branches. ugh
If you have resistances in parallel r1 r2 r3 and r4 the equivalent resistance is
1
___________________ = equivalent resistance
1/r1 + 1/r2 + 1/r3 + 1/r4
