just consider for example the AC voltage where the the voltage is given by V(t) = Vsin(t), for the duration of the positive part of the wave from 0 to pi/2 the capacitor would be 'charging' for that whole process and be at maximum charge at pi/2. then from pi/2 to pi, the voltage will be...

I was just wondering if it was possible theoretically to move or attract large/heavy materials using polarisation. For example I've heard examples that if you have a charged rod ,and you bring it close enough to pieces of paper the charge on the rod will polarise the paper and then if that...
