By wrapping some wires around a toroidal core, you can make a 75 to 300 Ohm matching transformer. It will cost you no more than $5. It will cost you nothing if you can find a few copper wires and…
The wire connecting the battery to the starting motor is crucial in supplying high currents for starting a vehicle. Selecting the right gauge wire ensures effective power supply, and voltage drop, and avoids electrical issues. In this article, we’ll look…
A multimeter is a versatile tool that can be used to measure a variety of electrical quantities. When working with electronic circuits and devices, measuring electric current in milliamps (mA) is common. But what does a 50-mA read mean on…
A 32-inch (LCD/LED/OLED) TV uses power in the range of 50-85 watts. But the number may vary depending on different factors. Such as resolution, refresh rate, and brand. Old 32-inch CRT TVs used to have a rating of 150-200 watts…
For 12/2 wire, the recommended conduit size is 1-1/4 inches. This is determined by the dimensions of the cable, which measure 0.463 x 0.183. To determine the number of wires this size of conduit can accommodate, a fill table based…
In decimal format, a 4-bit adder can operate between 0 and 15. An important part of digital circuits and computer systems is the 4-bit adder. It can add two 4-bit binary values to produce a 4-bit sum output and also…
Yes, it can. Mostly this can occur under two scenarios that are when there is already a large potential difference between you and the ground, and when a double fault has happened, and the “ground” wire is actually something else. In an electrical…
There are several ways to test a fuse without a multimeter including the light bulb technique, using an ohmmeter, visual inspection, etc. Using a fuse tester would be more accurate than using other instruments. A fuse is an electrical safety…
