DC output from a bridge rectifier.

[Rampage]

Been thinking about this. From standard UK 50Hz 230 Uo into a bridge rectifier the output would be 'b' on the drawing below?
Thanks.

Might B, can you explain why tho'?

i'll say b because 4 ------- are better than 2.

I did realise it looked like breasts after I drew it!

Fig B. Peak voltage *1.41 RMS
Fig A is half wave

yes B looks right, if it any help capactitors are used after rectifiers to smoth out the ac, ie draw a line at the top of all the waves, will never be a true line but near to dc as you will get.
So for telectrix, treat as a half cut bra to hide the -------....lol

Tel's aways half cut View attachment 14594

Because the negative half cycle rather than being removed is relocated into the positive half cycle.
Cant really think of how to describe it!

Fig A is half wave

So would the output RMS voltage be higher than 230v?
Figure A would be achieved by using one diode on the Line and one on the Neutral?

Just something I was thinking about while driving earlier.

326V from 230V AC
RMS *√2
