The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant. The other end, called the neutral...
The electrical service panel is where utility wires deliver electricity for distribution to the many circuits in your home. This Fix-It Guide tells how an electrical service panel works, what often goes wrong, how to identify the problem, and what parts and tools you will need to fix it. ...
Exercise caution with regard to the risk of electric shock since even household outlets carry a voltage of 100 V or 200 V. Additionally, moving the rotary switch causes the instrument to switch measurement circuits. Unintentionally inputting a voltage into the instrument while the resistance range ...

Thales ...
Electricity Basics - How Electricity Works & What Electricity Does in a Building Many years ago I [DF] asked an electrical engineer/programmer Daniel Martin and a physicist friend Trudy Kappel how electricity really works - what's really going on. The ensuing argument ended finally with "well ...
Current measurement shunts, or current shunt resistors, are resistors placed in the circuit for the purpose of measuring the current that flows across the shunt. These are fairly common electrical components and exist for a variety of applications. Sizing a shunt will be based on measurement curren...
Table lamps or floor lamps often have two or more bulb sockets, and rewiring these offers some different challenges than wiring a single-bulb lamp. Not only is there the main plug-in lamp cord feeding up through the base of lamp, but somewhere within the body of the lamp, this main cord...
Along with wiring and replacing the electrical panel, the cost to rewire a house also includes paying for new outlets and switches. More rooms means adding more circuits and other materials to your total. Electrical outlet installation costs an average of $215, including the $5 it costs to bu...

This is called a step-down transformer. If the second coil has half as many turns as the first coil, the secondary voltage will be half the size of the primary voltage; if the second coil has one tenth as many turns, it has one tenth the voltage. In general: ...
