# Resistors in Series

No matter how many resistors in series there are, two or ten, just specify the number of resistors and the resistance value for each one.

## Formulas that use Resistors in Series

\(R_t = R_1 + R_2 + R_3 + ... + R_n \) |

### Where:

\(R_t\) = total resistance

\(R_1\) = resistance of first resistor

\(R_2\) = resistance of second resistor

\(R_3\) = resistance of third resistor

\(R_n\) = resistance of number resistor
