| Electromagnet and Transformer for Sonometer PSAW
(1238 D ) |
|
These items are used to determine the frequency of A.C. mains by sonometer method. This apparatus consists of a suitable electromagnet with step down transformer of fixed voltage 6 V & 8 V and has a current capacity 2 A. When this attachment is supported over a sonometer and connected to a source of alternating current, The wire vibrates continuously. By adjusting the tension and the bridge position maximum resonance can be obtained. Supplied without sonometer and without stand for holding the electromagnet.
