In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of bang for the ...

I knew I was missing something important when as a mid-level electrical engineer, I used to wonder which voltage value I should be using in my calculations. Was it 110V, 115V, 117V, or 120V? Was it ...

An unavoidable reality of owning a car is the 12V battery. If the battery is healthy, it should read 12 or so volts, and you ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...
