A concern with a hot neutral is that it can shock you when you least expect it. A hot neutral wire is caused by a faulty wire, incorrect readings, an open neutral, and low resistance. Also, bad connectivity, high voltage, and…
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…
A regular bedroom LED light of 10W draws just 0.083 Amps. Because LED lights consume less energy than incandescent bulbs while producing the same amount of light. A 10W LED light can produce the same amount of light as a…
A failed capacitor is the most common cause of an AC not working. An Air Conditioner Unit may have capacitors in it. These capacitors are used to store energy and provide it to the AC fan and compressor motor upon…
You must measure either hot-ground or neutral-ground. Hot and neutral have been switched around if the neutral-ground voltage is around 120 V and the hot-ground voltage is a few volts or less. There should be some neutral-ground voltage when the…
With native USB, you can (sort of) break boards. If your code manages to overwrite some variables utilized by that specific USB code, you need to break the board. When you connect an Arduino to your computer, the Arduino descriptor…
There is no problem while using a 5v adapter to generate a 4.5v device. A device stating 4.5v actually can generally withstand a voltage appliance of a minimum of 5.5v. Hence there is no problem applying a 5v adapter to…
The motors will tremble and not turn if the appropriate stepper drivers are not providing enough current output. You should check your wiring as well. Ensure that all of your wires are connected and in the proper order. Typically, the…
To measure the ground resistance of an outlet, set the multimeter ohm setting to a value of fewer than 100 Ohms. Touch the two leads to the test wire and the test location. That should show the ground resistance on…
