Although there are three ways to find out the amps of your lights, the easiest one is to use the basic formula of dividing power in watts (W) by the volts (V) of voltage. For example, if the wattage of…

No matter how many DIY tricks you find on the internet, there are only three foolproof ways to solve the how-to trace coax cables dilemma. The solutions cater to everyone, regardless of the cash or effort they are willing to…

To convert percent transmittance to absorbance, there are two approaches. The first is the computation approach, while the second is the nomogram method. Transmittance values range from 0 to 1 and the percentage transmittance range from 0% to 100% where…

When it comes to electrical wiring, identifying which wire is positive and which one is negative is crucial. Often, wires come in various colors, but two of the most common are black and white. In this article, we’ll unravel the…

Typically, ceiling fans draw around 0.25 to 1 amp. Although, the amperage varies depending upon the model, speed settings, and such. You can determine the amperage simply by calculating yourself or by contacting the manufacturer. In most cases, the amperage…

There is no universal breaker size for water heaters, for they have different ratings of voltage, wattage, and, most importantly, amperage. Yet, if we had to generalize, a 30-amp double-pole breaker would be the one compatible with most water heaters…

Temperature is usually measured with bimetallic thermometers. However, they must be calibrated for their readings to be correct. Several methods can be utilized to do this. The method that is most suited to the specific thermometer and application is usually…

First, make sure to disconnect both ends and set your multimeter to the lowest resistance with a tone. Set a meter lead on either end of the wire. Your readings should be as low as possible and emit a tone…

There are numerous ways to test a capacitor to verify if it still works properly. Though you can also identify a bad capacitor just by looking at it. If the capacitor has a bulging bottom or a lifted case, it…
