Q of a coil

WebThe sharpness of resonance is defined using the Q factor which explains how fast energy decay in an oscillating system. The sharpness of resonance depends upon: Damping: Effect due to which there is a reduction in amplitude of vibrations. Amplitude: Maximum displacement of a point on a vibrating body which is measured from its equilibrium position. WebMar 24, 2024 · The ohmic losses remain comparatively low, so the quality factor Q will be huge near resonance. A Tesla coil employs this phenomenon to produce extremely high voltages in the range of several hundreds of kV. 7 Inductance calculators that do not show this real world behaviour are based on geometrical formulas.
