Theory
A set of resistors connected in parallel can be replaced by a single equivalent resistor with a value:- REquivalent = 1 / (1/R1 + 1/R2 + 路路路路路路路 + 1/Rn)
From this equation we can reach to some conclusions:
-
路 The resistance of the equivalent resistor is smaller than the smaller resistance of the set of resistors
路 When connecting two resistors with a very different resistance, the equivalent resistance is close to the value of the one with a lower resistance.
