Electrical equipment that operates below its voltage rating can overheat or power down. Here's how to determine your load's operating voltage. Voltage drop across switchgear and feeder and branch ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
