parallel resonance การใช้

For example, a crystal intended for a 6 pF load has its specified parallel resonance frequency when a 6.0 pF capacitor is placed across it.
When a " series " crystal is used in a Pierce oscillator, the Pierce oscillator ( as always ) drives the crystal at nearly its parallel resonance frequency.
When used at one particular frequency band the trap presents a very high impedance ( parallel resonance ) effectively truncating the element at that length, making it a proper resonant antenna.
Parallel resonance or near-to-resonance circuits can be used to prevent the waste of electrical energy, which would otherwise occur while the inductor built its field or the capacitor charged and discharged.
