Pump it Up The basic concept of an amplifier: A smaller current is used to modify a larger current. In the last section, we saw that an amplifier's job is to take a weak audio signal and boost it to generate a signal that is powerful enough to drive a speaker. This is an accurate...
A light bulb, for example, has a filament inside that is very resistant to flowing charge. The charge has to work hard to move along, which heats up the filament, causing it to glow. In building wiring, the hot wire and the neutral wire never touch directly. The charge running through...

The motors are usually placed either at the base of the steering column or directly on the steering rack and have become a fairly simple solution to advancing power steering into the 21st Century. Electronic sensors pick up the amount of steering lock being applied and add in a pro...
tap, the well pump is often to blame. A broken wire in the pump or leading to the pump can also cause a short in the pump. This short could also be why the breaker is tripping if it only does it intermittently. Lightning can damage a pump line, as well as vermin or advanced age...
Cartridge fuses are longer cylindrical devices that snap into a clip at either end. Cartridge fuses are used in fuse panels as the main fuse as well as to protect high-amperage circuits such as the 240 Volt circuits supplying an electric range, clothes dryer, or air conditioner circuit. In...
A portable generator is a convenient way to safely produce your own power when the grid goes down, either due to natural or man-made causes. But how does a generator work? Whether you’re new to using a generator, or well-experienced, there are a few things you need to ...
it might not be safe to drink, depending on the situation. If there is a boil order in place, remember that if the power is out, boiling your water may not be as easy as turning on your stove. If you are on a well and don’t have a back-up in place, you won’t have running...
