Those readers who have experimented with winding their own inductors will know that it’s not an easy task, and when those inductors are handling high voltages it can be especially tricky to maintain ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

High-voltage experimenters are a unique breed. They’re particularly adept at scrounging for parts in all kinds of places, and identifying how to put all manner of components to use in the service of ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

Transformers play a key role in delivering electricity from power plants to homes and cities. This video explains how they ...

Bob is a service technician who is well trained and nationally certified. However, he sometimes suffers from the same confusion that all technicians occasionally do - the facts that he gathers may or ...

MATERIALS that conduct electricity without losing any of it are the stuff that electricity companies dream of. In fact, they are far from being a pipe dream. All metals, as a Dutch physicist, Heike ...
