31. Mass flow meters have different resonant frequencies at different temperatures. 32. There may be several such series of resonant frequencies , corresponding to different modes of oscillation. 33. The valve operates to create three specific first-order resonant frequencies that increase cylinder air charge. 34. A large inductor will have a stray capacitance ( which creates its self-resonant frequency ). 35. If a resonator is enclosed in a metallic cavity, resonant frequencies change in following fashion: 36. Agree with Atlant, you need to find the inductance and then the self resonant frequency . 37. Thus the alternator output frequency is " locked " to the tuned circuit resonant frequency . 38. Higher tension and shorter lengths increase the resonant frequencies . 39. Light confined in the cavity reflects multiple times producing standing waves for certain resonant frequencies . 40. The self-resonant frequency is the lowest frequency at which the impedance passes through a minimum.
