# Resistors in Series

on . Posted in Electrical Engineering

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.

## Resistors in Series formula

$$R_t = R_1 + R_2 + R_3 + ... + R_n$$
Symbol English Metric
$$R_t$$ = total resistance $$\large{\Omega}$$ $$\large{\frac{kg-m^2}{s^3-A^2}}$$
$$R_1$$ = resistance of first resistor $$\large{\Omega}$$ $$\large{\frac{kg-m^2}{s^3-A^2}}$$
$$R_2$$ = resistance of second resistor $$\large{\Omega}$$ $$\large{\frac{kg-m^2}{s^3-A^2}}$$
$$R_3$$ = resistance of third resistor $$\large{\Omega}$$ $$\large{\frac{kg-m^2}{s^3-A^2}}$$
$$R_n$$ = resistance of number resistor $$\large{\Omega}$$ $$\large{\frac{kg-m^2}{s^3-A^2}}$$
