Having problems with your Fujitsu LifeBook C2330 Notebook ?

What is the ac polarity of a fujistsu lifebook c2330?


Answers :

In household and commercial electronics 110-125 AC has no polarity unless there is a safety ground, in which case the green safety is connected to to the white wire via earth ground. Black is "hot" meaning if you touch it you will feel a shock because your body connects the circuit to ground. A laptop operates on DC power delivered from an AC-DC converter usually around 20 Volts dc and 3.5 Amps, and charges the battery as well. Polarity of your computer is positive tip meaning the fat part of the plug going into the jack is ground, or negative, and the center is positive. I hope this helps.
