Can you tell whether a single moving charge constituite a current?Not necessarily steady current.I will be happy I we get a non-steady current.To have a non-zero current we need dq/dt not equal to zero.So at point in space,we measure dq/dt and it is 0 at time t,q at time t' and 0 again at time t".So at that point the current is q/(t"-t).Please justify...(adsbygoogle = window.adsbygoogle || []).push({});
