# Direct Current Confusion

I don't get DC. How do the electrons flow from one side to the other? Wouldn’t the electrons on both terminals just meet in the middle because of their attraction?

Electrons are repelled by negative charges (including other electrons) and attracted by positive charges. If I apply a positive charge at one end of a wire and a negative charge at the other, electrons will be attracted towards the positive end and repelled by the negative end, so will tend to move from the positive end to the negative end. There's no "meet in the middle" going on; no matter where in the wire the electrons are, they're being pushed by the negative charge behind them and pulled by the positive in front of them.

Well explained sir!
