Electricians know these electrical terms and you should too, especially if you plan to save money by doing basic electrical ...

Constant voltage transformers (CVTs), or ferroresonant transformers, produce a constant secondary (output) voltage for varying primary (input) voltages within a certain range. With CVTs, the ...

In his video [Afroman] describes how the LM317 can be used to regulate current rather than voltage to provide a constant current source under varying load. This can useful for a number of ...

Measuring the latter allows a constant power load mode (as power = current * voltage). In his article, [Kerry] shows that he can simulate a load of up to 200W.

A direct current flows in only one direction. On a voltage-time graph this would appear as a straight horizontal line at a constant voltage. Car batteries, dry cells and solar cells all provide a ...
