Demountable Transformer Kit

Inspire have redesigned the classic demonstration apparatus to address the safety issues in the conventional apparatus. The conventional design always had the chance to generate lethal voltage if a wrong primary -secondary combination of coils were used. Using the purpose-designed power supply, no voltage greater than 25V ac can be experienced in whatever combination of primary – secondary coils the user selects. Also, the wings of the specially designed coils prevent any wrong combination to generate high secondary voltage. The 25 V ac output terminal of the power supply cannot be connected across the ordinary coils to make step-up or step-down transformers and hence safe. Only specially designed coils with special connectors join to the 25V ac terminal.

RESONANCE APPARATUS SIMPLE

Stationary waves are produced by the superposition of two waves of same frequency and amplitude travelling with same velocity in opposite directions. Due to the constructive interference, these waves produce certain fixed points along the medium which undergo zero displacement. These points of no displacement are known as nodes. Midway between every nodes are regions of maximum displacement. These points are called antinodes.

  • Distance between node and antinode is λ/4
    where λ is the wavelength.
