resistors do resistor stuff.

## resistors in series

Their resistance add!

\begin{equation} R_{eq} = R_1 + R_2 + \dots \end{equation}

**CURRENT** remains the same through the resistors.

## resistors in parallel

Their resistance add by inverse fraction!

\begin{equation} \frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \dots \end{equation}

**VOLTAGE** remains the same through the resistors.
