Video answer: What happen if ac square wave to transformer
Top best answers to the question «Is a square wave ac or dc»
The 240 volt mains power supplied by the electricity grid is AC (Alternating Current)… "Square wave" is the term used when the electricity has a constant force, such as it has with DC but switches direction more or less instantly at the same kind of frequency as the normal grid supply (at 50 times per second).
- So it is not "AC" in the traditional sense, however it is an alternating waveform, and does exhibit all of the characteristics of AC signals. So it can be looked at in both ways - as two DC voltages varying with time, and also as an AC squarewave, just with a DC bias that happens to place the lower edge at 0 volts.
