Question 3
Hay bridge is suitable for measuring inductance of which one of the following inductors?
Question 4
The bridged-T network circuit shown above can be used for determination of inductance and Q of R.F. coils. Lz and Rx are unknown parameters of the coil. Using equations for balance, what are the values of Lz and Rx?
Question 5
A Q-meter is supplied with an oscillator having a 500 mV output voltage. While testing an unknown inductor, the voltage across the variable capacitor of the Q-meter, measured by a digital voltmeter, is obtained as 10 V. The Q-factor of the inductor is
