Introduction This is the first in a series of Power Supply articles I am working on. Each will evolve in complexity, function, and practical application. Before starting power supply experiments, review and follow electrical safety procedures. Here is a short article I wrote on Electrical Safety. Given Given: Vpri = 120v 60Hz, Turns ratio = …
Safety First The wall outlet at your house is 120-volt rms. 120vrms is dangerous. The circuit breaker at your house, which acts like a safety switch turning off the voltage when a maximum current has been exceeded, has a maximum current rating of 15 to 20 amps. Death can occur from as low as 100mA …
