# Why does electric current flow into circuits?

It may not be correct to say that an electric current will "flow into" circuits. Electrons move in a circuit in response to an applied voltage. And these electrons are alread in the circuit and available to support current flow if a voltage is applied. It may be more correct to say that electrons (MORE)
