The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

The newly cloud-connected Leviton Load Center features intelligent circuit breakers that you can control or monitor from your phone. Originally hailing from Troy, Ohio, Ry Crist is a writer, a ...

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 ...

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 ...

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

This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...

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 ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...
