Frequently asked questions
Regarding alternating current in the context of an AC line supply, a polarity test is done to ensure that the line and neutral line conductors are connected the correct way.
DC flows the Line in one direction, which results in constant polarity. AC flows half the time in 1 direction. accepted wiring convention is that the red wire line carries the positive voltage.
An important aspect of any voltage Line value is its polarity. AC Line Voltage is an energy level difference between two points, and the polarity of the voltage Line simply indicates which point has the higher energy level.
The anode (longer lead) is the positive lead and the cathode (shorter lead) is the negative lead. direction reverses at the supply frequency, so AC line has a different definition.
current direction alternates between the two poles. Therefore, we have to confirm the terminals before connecting any device. You can determine it by doing a simple polarity test Meter.
