DIY Kit 125 - NEGATIVE ADJUSTABLE POWER SUPPLY
... The regulators supplied in Kits 124 & 125 are capable of supplying 1.5A over an input voltage range of 1.2V to 37V. They need at least a 2.5V input-output voltage differential. In practice the limiting factor on the output voltage & current will be the power dissipated by the regulator. For example, ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
