What is the impedance of two impedances in series?

Explanation:
In series, impedances add because the same current flows through both elements. Impedance relates voltage and current by V = IZ, so the total voltage is V_total = V1 + V2 = I Z1 + I Z2 = I(Z1 + Z2). That makes the total impedance seen by the source Z_total = Z1 + Z2. This holds for any type of impedance, real or complex. If the impedances were in parallel instead, the total would be (Z1 Z2)/(Z1 + Z2).
