Parallel RLC Impedance Calculator — Admittance, Phase & Resonance
Calculate ideal parallel RLC admittance, impedance magnitude, impedance phase and resonant frequency from R, L, C and frequency.
Results
|Z| 103.2623 Ω
Admittance 0.009684079 S
Phase(Z) 84.07294°
Resonance 1,591.549 Hz
Formula and assumptions
Y=1/R+j(ωC−1/(ωL)); |Z|=1/|Y|.
At ideal parallel resonance the reactive admittances cancel and impedance is governed by R.
- R, L and C are ideal parallel branches.
- Parasitic losses are not modeled.
Frequently asked questions
Why use admittance?
Parallel branch admittances add directly, making the calculation deterministic and less error-prone.
Is resonance infinite impedance?
Only an ideal lossless LC branch can imply that limit; a finite parallel R keeps impedance finite.
