The steep dependence of channel opening on membrane voltage allows voltage-dependent K + channels to turn on almost like a switch. Opening is driven by the movement of gating charges that originate ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

Fig. 1. Basic single-phase circuit and load. As the load draws current, a voltage drop develops across the supply and return conductors. N-G voltage measurements at the load will reflect the voltage ...

Whether you’re aware of it or not, three-terminal voltage regulators automatically adjust power supply voltages in everything from audio consoles to distribution amplifiers to audio processing to STLs ...
