The voltages across three resistances R₁, R₂ and R₃ connected in series are V₁, V₂ and V₃, respectively. What is the net voltage V across them if I represents the net current flowing through them?
\(V=\frac{1}{V_1}+\frac{1}{V_2}+\frac{1}{V_3}\)
\(V=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}\)
V = V₁ + V₂ + V₃
V = R₁ + R₂ + R₃
