Hi All, I have a 110V, 20A household electrical circuit that has current but no voltage. If I shut down the circuit break and no voltage or current is present at a plug (checked with Volt/OHM meter as well as a Voltage/Current tester) and then turn on an overhead light (three-way switch) in the...
Is there a way to test for current via the hot only? For example, could you test the black wire only, or do you have to have neutral or ground to test?
My qustion is if there are one colsed circuit one battery and a lamp,then If the voltage to lamp is zero v=0 and current is some value greater than zero. Will the lamp glow? And in other case I=o and v= >0 will the lamp glow. In which case lamp will glow and why?
I work for a cable company and we have this phenomenon called voltage feedback. It breaks down into two parts. First part is we read an AC voltage between the coax and house ground, which we say is "floating voltage". Second part is where we grab the coax and touch the ground and get a "tingle". ...
What is voltage,current and resistance? Thanks:) Would help a lot!
