Resistors in series - formula in LaTeX
In a series connection the resistances add up and the same current flows through every resistor. The ellipsis is \dots: with the amsmath package LaTeX centers it between the plus signs, which three plain periods would not do.
LaTeX code
$$
R_z = R_1 + R_2 + \dots + R_n

What the symbols mean
- equivalent resistance (Ω)
- resistances of the individual resistors (Ω)
An electricity and magnetism formula - the basis of circuit problems and electrical lab reports.
Worked example
Three resistors of 100 Ω, 220 Ω and 330 Ω connected one after another. Write the unit after every number or once after the parentheses; just do it the same way throughout the document.
