Some audio amplifiers employ a high current capable technology, powering loudspeakers with robust levels of electrical current. The dynamics of music means a speaker's demands for current vary widely from one moment to the next. A high current capable amplifier has extra reserves of current, producing enjoyably loud music with low distortion.

A sink console is essentially a table without a tabletop so that a counter and sink unit may be dropped into the opening. Console sinks may have two or four legs; a two-legged console mounts to the wall on the backside, while a four-legged console may be left freestanding. Purchasing a prefabricated console for your sink could seriously dip into your bathroom budget, but you can build your own using basic lumber materials and tools. Purchase the countertop sink first to use as a guide for building the console.
Traditional face-frame cabinets use narrow strips of wood to frame the opening of the cabinet box, to which the cabinet doors attach. This style of cabinetry exposes the cabinet door hinges, helps ensure the front of the cabinet is square and generally uses double-width stiles. Before installing face-frame cabinets, bear in mind that you will have less overall cavity space. The advantage, however, is that you will have more door-mounting options available to you than if you used frameless cabinetry. To frame a cabinet opening, you will need intermediate carpentry skills and have the ability to make pocket holes.
The non-profit American National Standards Institute seeks to enhance the global competitiveness of American businesses by providing standards and guidelines for a wide spectrum of applications. From development to application, ANSI standards affect products in fields as diverse as livestock production, construction equipment and energy distribution. ANSI C12.1-1995, which the institute made effective in January 1995, serves as standard for permanent meter products such as those used by utility companies to measure energy usage.
Using electrical resistance alone, you can reduce a DC power source from 12 volts to 9 volts. Two elementary laws of electricity, known as Kirchoff’s and Ohm’s laws, govern the principles behind this form of voltage reduction. To accomplish the voltage change, you need two resistors in a series circuit. The proportion of resistance between the resistors determines the voltage across each, and a simple calculation tells you which resistor gives you 9 V.
A horse's conformation, or its proportionate dimensions, is often a good indicator of his athletic abilities and talents. The shoulder angle on a horse is commonly measured as an indicator of the scope of the horse's gait and smoothness. The angle of the shoulder, combined with the rest of the animal's conformation, may be evaluated or judged during competition.
Old brick chimneys add a focal point to the roof line of historic homes, reminding passers-by of an era where every home was heated with wood or coal fires. With the invention of central heat and air, however, many of these older chimneys have fallen into disuse and disrepair. Often when older homes are re-roofed, abandoned chimneys are removed to a point just below the roofline in the attic. This creates a problem for the homeowner who wishes to build into the attic space. The portion of the chimney in the attic can be leveled with the floor with the…
An exterior arch is built by forming a rough arch out of pieces of wood that are then cut and sanded into a smooth curve. The curves are then mounted on top of sturdy wooden frames, often with a trellis attached between the two frames required to form the arch in its entirety. When plants grow up the trellis, the arch becomes a decorative centerpiece for a garden display.
KAIC is an acronym used by electricians to refer to the ability of a circuit breaker to withstand a short circuit or overload. Large industrial circuit breakers often include a rating in KAIC that indicates the circuit size with which they are compatible. Choosing the correct breaker for your system prevents serious problems if there is a short.
An evaporator coil serves an essential function in a heating, ventilation and air conditioning (HVAC) system by removing heat from air in order to cool interior environments. Installing a new evaporator coil is a relatively simple process and only requires a handful of tools. Always obtain an installation manual from the coil manufacturer, before beginning installation, as each brand and model of coil may require slightly different installation methods.
An electromagnetic field is a physical field produced by electrically charged objects that are moving. This type of field is often surround electrical devices such as power lines, electrical wiring and electronic appliances. A number of materials can block EMFs and each can be cut to meet your specific needs and shaped by hand. If you want to make an EMF blocker for your magnet, motor or appliance, you can do so with any EMF-shield material.
Soffit is installed on the underside of decks to protect the space below to create a finished surface beneath the deck. Soffits built underneath decks can use plywood or vinyl sheathing. Angling the soffit will allow water to run off and help prevent water damage to the soffit.
Mac OS X installation files don't come in EXE format as they do on a Windows computer. Instead, you install applications via DMG files that are mounted automatically when you double-click them, causing the computer to treat each file like a CD or DVD disc and creating a removable device icon for the file on the computer's desktop. If you have a USB stick with Mac OS X installed on it, you must use DMG files to install applications, just as you do when booting from an internal hard drive.
