I'd like to get more into home automation with Homekit, but finding most smart light switches and outlets require neutral wires. I have an old house and rewiring it to add neutral wiring isn't an option. Any suggestions on what can be done with an older house?J...
Until now, these two separate pieces of silicon were electrically neutral; the interesting part begins when you put them together. That's because without an electric field, the cell wouldn't work; the field forms when the N-type and P-type silicon come into contact. Suddenly, the free elec...
Why do outlets have two ground receptacles? Define electrostatic. State and define the household units of electricity. Why is earthing of outer surface of a cylindrical capacitor needed? Why is it necessary to have an earth wire installed in a power circuit, but not in a lightening ...

Appliances that need DC but have to take power from AC outlets need an extra piece of equipment called a rectifier, typically built from electronic components called diodes, to convert from AC to DC.An inverter does the opposite job and it's quite easy to understand the essence of how it ...
almost 300 entries, Rappler’s investigation into murders in Manila’s drug war won big in the Large Outlets category12. This win is huge because it points out how important good investigations are. They help people know what’s really going on and push for changes that make a difference....
CONNECTIVITY: Looking for a convenient place to dock a smart phone or plug into USB ports? We all know that it's a hassle to crawl below your desk to plug into USB ports and electrical outlets, and that there are times when you'd just rather not have to deal with an iPhone® charg...
circuits may have two hot wires alone or a third, neutral wire may be added. In all cases, the hot lines are attached directly to the hot main buses. The neutral wire is always connected to the ground bus and never, under any circumstances, should it pass through a fuse or circuit ...
Step-down transformer: Once the electricity reaches its destination, another transformer converts the electricity back to a lower voltage safe for homes to use. Homes: Electricity flows into homes through underground cables. Appliances: Electricity flows all round your home to outlets on the wall. ...
National Electrical Code in 2002 first added AFCI protection, for bedrooms outlets. In 2008, coverage was expanded to all living areas, also adding that only "Combination AFCIs" are allowed. Manufacturers and UL claim that arcing across a break in a cord's conductor is hazardous, and that a...
