My science teacher gave me this formula for resistance in parallel circuit.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{1}{R_{eq}}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+.....[/tex]

Thats exactly how he wrote it.

I would like this using the summation sigma

[tex]\frac{1}{R_{eq}}=\sum_{R=\frac{1}{R_n}}^n[/tex]

Is that right? Im sure it's not lol....
