getcalc.com's **RLC Circuit Equivalent Resistance (Z _{eq}) Calculator** is an online electrical engineering tool to calculate resultant resistivity for resistor (R), inductor (L) & capacitor (C) connected in series or parallel.

## Definition & Formulas

**Equivalent Impedance**, often abbreviated as Z_{eq} in electrical engineering, is a measure of whole combined resistivity of RLC circuit resistor (R), inductor (L) & capacitor (C) connected in series or parallel. The measurement unit for impedance is Ohms (Ω).
