The rotor is a series of large electromagnets that spins inside a tightly-wound coil of copper wire, called the stator. The magnetic field between the coil and the magnets creates an electric current. In the Hoover Dam, a current of 16,500 amps moves from the generator to the transformer,...

Effective load management is necessary when adding new outlets to a circuit. To compute the outlet count, multiply the amps with volts to get how many watts the circuit can support. Most countries, including the USA, use a 120-volt circuit. For a 20-amp circuit, the total number of volts...
Also look for old plugs that don't fit snugly into an outlet. These can also cause sparking, which is bad when the outlet is next to a dead pine tree brimming with flammable sap. Ultimately, you can't tell how many plugs are too many before an outlet will catch fire, except on a ...

120 Volts / 0.015 Amps = 8000 Ohms Take a resistor of about 5000 or 6000 Ohms and wire it between the hot (Narrow blade) and ground pin of a male cord end. The GFCI should trip when the plug is inserted into the GFCI. Note: The ground terminal of the GFCI must be connected back...
Do you need to plug in an electric kettle, a floor lamp, or a refrigerator? In all of these cases and many more, you'll need a 120-volt power outlet, more correctly called a 120-volt receptacle. Every house in North America has them unless the house happens to be off-grid and powe...

Matter, as you probably know, is composed of atoms. Break something down to small enough pieces and you wind up with a nucleus orbited by one or more electrons, each with a negative charge. In many materials, the electrons are tightly bound to the atoms. Wood, glass, plastic, ceramic,...
In many cases, humans are considered to be good conductors of electricity and provide a viable pathway for electrons to flow. If a person dies through electric shock, their death is classified as electrocution. What is the safe voltage for a human body? Voltages above 50 volts are dangerous...
