| Equivalent Circuit |
 |
| The following electric circuit can be used to model a resonance / anti-resonance pair that exists in the electrical impedance of piezoelectrics. |
 |
| The following 2 conditions are required for the circuit to accurately simulate piezoelectric resonance behavior: | |
 |
The value of C must be much smaller than Cp |
|
C and Cp in parallel must equal the piezo's low-frequency capacitance |
| The frequencies (in Hz) of the electrical resonance and anti-resonance are given by the following equations (which assume a small series resistance R): |
 |
