Too much charge flowing through a circuit at a particular time would heat the appliance's wires and the building's wiring to unsafe levels, possibly causing a fire. This keeps the electrical system running smoothly most of the time. But occasionally, something will connect the hot wire ...
Finally, connect the battery by attaching one end of the wire to the positive terminal and one to the negative terminal (it doesn't matter which end of the wire gets paired with which terminal). Presto! A working electromagnet [source: Jefferson Lab]. Can't get enough of hands-on electro...
Let's say you have a 120-watt light bulb plugged into a wall socket. The voltage is 120 volts, and a 120-watt bulb has 1 amp flowing through it. You can calculate the resistance of the filament by rearranging the equation: R = V/I So the resistance is 120 ohms. Beyond these core...
You’ll also find a plastic cord that’s used to strengthen the headphone cable: The TRRS plug connects to the wires like this: If you can get to the pins inside the plug’s housing, the pins of the TRRS plug connect like this: ...

You simply crack the ATA out of the box, plug the cable from your phone that would normally go in the wall socket into the ATA, and you're ready to make VoIP calls. Some ATAs may ship with additional software that is loaded onto the host computer to configure it; but in any case,...
Note: Please connect a 1K resistor across the filter capacitor associated with the bridge rectifier, this is to ensure its quick discharging during a mains failure, and an instant switching of the relevant relays. Main Components and Their Functions: ...
When the telephone company initially installs a phone line into a home, they should provide at least one phone jack to connect a telephone. The easiest phone service test is to merely plug a phone into this jack with the proper wire, take the phone off the hook, and listen for the dial...
Plug one end of the phone wire into the phone jack provided on the router’s back Plug the other end of the phone wire into the wall jack of the phone connection. If you are using a splitter, connect this end of the phone wire to the splitter socket that says DSL. You can then us...
It’s small, with a swing-out catch to hold it on your laptop’s display, and it even has a little fold-out ring that lets it pull double-duty as a phone kickstand or pop socket stand-in when you’re not securing it to the laptop. It’s sturdy and covered in a soft-touch ...
