Consider the following statements regarding sources of error in a Q-meter: 1. If a coil with resistance R is connected in direct measurement mode and if the residual resistance of Q-meter is 0.1 R, then the measured Q of the coil would be 1.1 times the actual Q. 2. If the inductance to be measured is less than 0.1 mH, the error due to presence of residual inductance cannot be neglected. 3. The presence of distributed capacitance in a coil modifies the effective Q of the coil. Which of the above statements are correct?
