Hi Everybody,
Just wondering if someone can explain negative volts & amps, ok i understand positive voltage & amps but negative?
Has negative voltage & amps got the same grunt as positive volts & amps??
Just say there is a negative going square wave of -10v & -1A going into an inductor, is this the same as charging the inductor with +10v & +1A.?
If so then by increasing the amperage to say -2 amps will this will increase the field strength around the inductor?.
Just seems all upside down to a newby??
