Consider the following statements regarding the sources of error in a Q-meter:
1. If a coil with a resistance R is connected in the direct measurement mode and if the residual resistance of the 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 i.e. less than 0·1 μH, the error due to the presence of residual inductance cannot be neglected.
3. The presence of distributed capacitance in a coil modifies the effective Q of the coil. Of these statements:
