Making wire wrapped jewelry is the perfect hobby for those who are interested in crafting metal jewelry but aren't ready for the commitment of setting up a metal-smithing studio. Determining the correct wire gauge for these projects is somewhat up to creative license, but here are some general...
According to good engineering practice, line performance losses should be kept below 0.5dB or a maximum of 0.25 dB. Factors that lead to this loss include impedance of the speaker, cable length, cable gauge and amplifier impedance. Suggested wire gauges for different distances and impedances are...
Examine the variables in calculating the wire size. The primary variables in each method are the size of the rod used to start the drawing process and the reduction ratio of each draw. Determine the size of gauges larger than 0 gauge. These are calculated by applying the same reduction ratio...
Refer to the reference charts in your "Ugly's Electrical Reference" or "Audel Mechanical Trades Pocket Manual." (The chart is called "Current Capacities" in the Audel book.) You'll see that a two basic factors will determine the correct choice. First, what kind of wire is it? That is...
AWG is for single-strand, solid, round, electrically conductive wire. It was first introduced in 1857 as a standard to replace the various measurements used by different manufacturers. Use of larger numbers denoting smaller wires is similar to Standard Wire Gauge, which is used in Britain. Most...
Standby generators for home and small commercial applications connect to loads using the standard 120/240V electrical system. The appropriate wire size depends on the voltage, the current, the circuit breaker at the generator and the length of the wire. The wire must be rated for the system vol...
Failure to take this step risks a fatal electrical shock. Place cable on a solid flat surface. Determine the length of insulation to be removed. The cut through the plastic wire jacket should be six to eight inches long. Some electricians spread their hand wide and use the distance between...
It goes through open air for about 2 feet and there is no way to secure it to anything. Thanks! Tom - 7/19/12 Reply: You need to look at the type and rating of the electrical wire to determine if it is permitted to bury it in concrete or not. ...
Relays use an electromagnet to mechanically switch a circuit on or off, allowing a small amount of electrical power to control a much larger power load. Commonly found in both household appliances and vehicles, relays enable electronic controls to operate high-power circuits like motors and lights...
c. Determine whether to connect internally or externally; d. Connect the circuit; (2)Operation Adjust the sliding rheostat, read the ammeter and voltmeter in turn, and record the table. (3) Data processing Method A. Calculate each resistance by mathematical calculation and then calculate the ave...
