Resistors in Series

Written by Jerry Ratzlaff 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

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


 Units 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 \(\large{\Omega}\) \(\large{\frac{kg-m^2}{s^3-A^2}}\)
