I know that DC can be graphically explained as unidirectional flow of electric charge.
Also I know in AC, electric charge would move forward, then backward on and on.
I also know that DC usually comes from battery and AC comes from the house wall.
That's all I know. Just the definition.
Please tell give me some example and help me further understand these two things. Anything that I didn't mention above that'll help me understand it more. I did look up on the net & wikipedia but it's confusing.
