The Real Difference between DC and AC #electricity #physics #engineering

When people think DC, they usually visualize a straight-line graph. The reality is that any waveform with only one polarity is DC. In a circuit, this means that the current only flows in one direction.

On the contrary, when people think AC, they usually visualize a sine or cosine. The reality is that any waveform with two polarities is AC. In a circuit, this means that the current switches direction every half cycle.

DC, because it doesn't exhibit value change.

Is it DC because the value remains negative?

I believe DC because the graphs sign does not change
