In capacitive circuit, the voltage and current are out of phase. the current leads the voltage by 90 degrees. this can be explained by these two equations:
V=Vmaxsinωt
I=Imaxcosωt.
Now, my question is that what does this statement mean physically that "current leads the voltage by 90 degrees? It is clear mathematically that if V=0 then I is maximum but how do we explain this physically? hope you understood my question
