[QUOTE="apprentice87, post: 443736, member: 13534"] Yes, that link is correct.. as the man says, when there is nothing connected, no power is used. BUT, in his example of the "device" plugged in but switched off, he is correct. This is because the swtich is in the secondary winding of the transformer, the primary is still connected across the mains. Likewise, i am led to believe, that when a television is switched off by the remote control, that it is still using power [I have not got a telly and do not want one and know nothing of such devices] This is obvious, [that it still uses power] because its circuitry is still operational, "waiting" for a signal from the remote.. BUT, you are on about when there is NOTHING even plugged in, that is completely different.. Is this bloke trying to sell you something?? john.. [/QUOTE]
