About This Product
A demountable transformer can be taken apart, so students see the coils and the iron core separately and then assemble them. With a primary and secondary coil on the closed core, they measure the voltage across each and show that the voltage ratio follows the ratio of turns. Changing the coils or tapping points gives step-up and step-down cases, and opening the core shows how much it matters that the magnetic circuit is closed.
Frequently Asked Questions
Q1. Does the Demountable Transformer need an external power supply?
No. The 600 turn coil is provided with a power supply cable, so an external power supply unit is not required.
Q2. Which coils are supplied?
Coils of 6000, 600, 1200 and 72 turns are described. Any other coil of different turns is listed as available on request.
