A piezoelectric buzzer sounds at a specific frequency when the voltage across its terminals exceeds the set voltage. The buzzer is simulated as a single resistor whose resistance value is dependent on the buzzer’s rated voltage and the current. It beeps when the voltage across its terminals exceeds its voltage rating, Vrated. Buzzer resistance r= V rated i rated Beeps when V ab ≥ V rated National Instruments Corporation 11-9 Multisim Component Reference Guide
