A high Q coil having distributed (self) capacitance is tested with a Q-meter
Q. A high Q coil having distributed (self) capacitance is tested with a Q-meter. First resonance at w1 = 106 rad/s is obtained with a capacitance of 990 pF. The second resonance at w2 = 2 ×106 rad/s is obtained with a 240 pF capacitance. The value of the inductance (in mH) of the coil is (up to one decimal place)
Ans: 0.9 – 1.1
