current would need to be infinite for this. Why is this. Can anyone show the maths behind this? Cheers!(adsbygoogle = window.adsbygoogle || []).push({});

*EDIT* ok i just did some maths on a basic RC circuit. If t approaches zero then the current simply approaches -(Vi/R).. which isnt infinite. This is why i can't grasp this. I would love to see the theory behind why this is. TY
