Replacing a capacitor with something that has a higher voltage rating is always safe. The only problem there is that a capacitor rated for a higher voltage is often physically Read more

It doesn’t matter which end of the fuse holder gets used for going to the battery and which goes to the jack. Fuses don’t require current to flow through them Read more

1/ As a general rule you can run single phase loads off a 3 phase generator but as noted it is better to try and balance the loads across the Read more

120v and 125v outlets are nominally identical. You must have something miswired, or you have a rare faulty unit. Be sure you have power connected to the LINE side. What Read more

To some degree, Nickel Metal Hydride (NiMH) is interchangeable with Nickel Cadmium (NiCd) — with caveats. The issues related to replacing NiCd with NiMH are the charge methods, the discharge Read more

These unwanted perturbations (if not controlled) can couple directly into the circuit and cause instability or damage. In this case, the bypass capacitor is a first line of defense. It Read more

The battery will have a high current discharge and will heat up. It is recommended to preserve the battery against strong shocks. In case of usage: This occurs when a Read more

You would most likely damage your meter, and could possibly create an “over-current” situation in the circuit you’re trying to test. Can I use multimeter on live circuit? Testing whether Read more

You cannot use that adapter because it is outputting more voltage than the original (12v vs. 9v). This has a likely chance of burning out one or more of the Read more

The device will be burnt [the power unit]. Next, If a 220V/240V device is connected to a 110V/100V supply line, NOTHING will happen. No harm. Is it OK to plug Read more
