All Brian's points are incorrect except that they do often get stiff
due to limescale or corrosion.
A diode will give 240v x 0.707 rms volts, which is more than 120.

No, it will be 50% of the AC waveform, less a bit for the fraction of
a volt lost across the junction.

do you ever get anything right?

Yes, quite often actually and I am right this time too.

Dont see tabbypurr as he is plonked, but yes, he is talking cock and for
a resistive load, a diode will indeed halve the power.

Half power yes, which equates to 240v x 0.707 rms volts, as I said. Wakey wakey.
