AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and ...

DC waveforms are roughly constant, and what matters is the distance from zero. AC waveforms are always wiggling around a center point, and this is often ground.

AC vs DC: Know here what is the difference between AC and DC. AC stands for alternating current whereas DC stands for Direct Current. Check key dissimilarities here.
