Resonant system

Item no.: XWV550010 Description This original apparatus gives students a modern approach to a fascinating topic with great scope for imaginative research. An acrylic base unit supports a steel strip which is loaded at the top with a detachable brass weight. An electromagnetic drive coil, connected to a standard laboratory signal generator can cause the strip

Coupled resonant circuits

Item no.: P2450201 Principle The Q factor of oscillating circuits is determined from the band width and by the Pauli method. In inductively coupled circuits (band-pass filters) the coupling factor is determined as a function of the coil spacing. Tasks Determine the dissipation factor t and k and the quality factor Q from the band
