# How can I calculate resistance of a parallel circuit?

Apr 30, 2018

$\frac{1}{\text{Resistance(in parallel)" =(1)/"Resistance 1"+1/"Resistance 2}} + \ldots \ldots$

#### Explanation:

For 2 or more resistors in a parallel resistance can be calculated by

$\frac{1}{\text{Resistance(in parallel)" =(1)/"Resistance 1"+1/"Resistance 2" + 1/"Resistance 3}} \ldots \ldots .$ and so on.

For two resistance can be calculated by

$R e s i s \tan c e = \frac{R e s i s \tan c e 1 \cdot R e s i s \tan c e 2}{\text{Resistance 1 + Resistance 2 }}$
