Lab 5-8 Equations

The equation for resistors (light bulbs) in parallel is:

\(R_{Tot}=\frac{1}{\frac{1}{R1}+\frac{1}{R2}+\frac{1}{R3}+\:.\:.\:.\:.}\)

We have 2 resistors so it looks like this.

\(R_{Tot}=\frac{1}{\frac{1}{0.7}+\frac{1}{0.7}}=\:\frac{1}{1.42857+1.42857}\:=\:\frac{1}{2.857143}\:=\:0.35\)
