m sub-sub-headings for "Conductance", and say "simply" instead of "reads"
Line 44:
Here, the subscript ''s'' in {{math|''R''<sub>s</sub>}} denotes "series", and {{math|''R''<sub>s</sub>}} denotes resistance in a series.
 
==== Conductance ====
[[Electrical conductance]] presents a reciprocal quantity to resistance. Total conductance of a series circuits of pure resistances, therefore, can be calculated from the following expression:
<math display="block">\frac{1}{G_\text{total}} = \frac{1}{G_1} + \frac{1}{G_2} + \cdots + \frac{1}{G_n}.</math>
Line 119 ⟶ 120:
An old term for devices connected in parallel is ''multiple'', such as multiple connections for [[arc lamp]]s.
 
==== Conductance ====
Since electrical conductance <math>G</math> is reciprocal to resistance, the expression for total conductance of a parallel circuit of resistors readsis simply:
<math display="block">G_\text{total} = G_1 + G_2 + \cdots + G_n.</math>
