E6D02 — Amateur Extra Class

E6D02 : What is the equivalent circuit of a quartz crystal?
A Series RLC in parallel with a shunt C representing electrode and stray capacitance
B Parallel RLC, where C is the parallel combination of resonance capacitance of the crystal and electrode and stray capacitance
C Series RLC, where C is the parallel combination of resonance capacitance of the crystal and electrode and stray capacitance
D Parallel RLC, where C is the series combination of resonance capacitance of the crystal and electrode and stray capacitance
Correct Answer: Series RLC in parallel with a shunt C representing electrode and stray capacitance
