While learning about current, the text states that charge/current is not consumed. KCL shows this as does the law of conservation of energy.
What I don't understand intuitively is how charge/current is not consumed if they produce work?
In more concrete examples we see energy given off with a resultant change in the materials, i.e. - Fire, gives off heat, light, etc. while consuming the energy source (wood was the source of potential energy until liberated by the fire).
Can someone explain this to me with respect to how current in electricity is not consumed, yet still does work?
Thanks!
