This inductancd standard is for use in such experiments as determination of resistance, determination of the ballistic constant of galvanometers on open and closed circuits, and in the measurement of mutual inductance by comparison. | |
The primary consists of 500 turns, with a resistance of 2.5 ohms. The secondary is 600 turns in three layers, with taps at 200 and 600 turns. The resistance is 150 ohms. The mutual inductance coefficient when using the 600 turn secondary is 3.2 millihenries. |
