On the right hand side the voltage changes polarity everytime, now, that I 'earth' one of the wire, its now called Neutral, which is 0V(for convenience), and voltage alters in the live wire between +240/-240. My question is this transition true and instant?

and if you could help, I don't really understand how does 'earthing' the wire suddenly makes it 0V, isn't the wire still connected to the source which offers 240VAC?
