The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

A perfect example of how a circuit overload can be dangerous occurred as my caregiver friend tried to relieve the excessive heat affecting her 100-year-old client. The solution seemed simple: plug in ...

When a circuit is pushed past its limits, it rarely fails politely. It signals trouble through tripped breakers, hot outlets, ...

The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and ...

Leviton has unveiled its next generation electrical Load Center. The new breaker panel works with an integrated Wi-Fi or Ethernet hub to offer remote circuit control, monitor electrical consumption, ...

Leviton has announced a new version of its Load Center breaker box for homes, and it’s adding an integrated Wi-Fi or Ethernet hub that will let you manage your home electrical setup directly from your ...

Design prevents powering-up a load such as a microprocessor with a solar array when available light is insufficient to sustain operation. Fig 1. The solar array supervisor includes a dummy load ...
