The idea of current has been presented to me so many different ways I thought id try and find out a little more into what exactly is current.
Most places refer to a flow of charge as a current, seems good to me, but - I heard the current may flow outside the wire in... I want to say charge desnty fields but don't quote me on that... Is this is case? if so how?
Secondly the concept of "current flowing" seems to me very strage - if current = [itex]\frac{\delta q}{\delta t}[/itex] surely this implies the "current flow" people speak of is : [itex]\frac{\delta^2 q}{\delta^2 t}[/itex] ?
Thank you for your help.
