**Conductance**is the

*reciprocal*of resistance,

i.e. Conductance G = (1 / Resistance)

*Unit*s of Conductance are Siemens (

**S**)

**Calculating Resistors in Parallel Using Conductance**:

G = G1 + G2 + G3 .....

(Total conductance is greater with more resistors in parallel so resistance is less.)

**Calculating Resistors in Series Using Conductance:**

(1/G) = (1/G1) + (1/G2) + (1/G3) .....

(Total conductance is less, because resistance is greater.)
