the dc ectified voltage will be 230 v only.....

Answer / jaywant

230volts only

Answer / guest

dc output value will be actually the rms value.
RMS value of input=230 volts
max value of input=230*sqrt(2)=325.27 volts
since no transformers are used,
max output=325.27 volts
Therefore,dc output voltage=rms value of 325.27=
(2*325.27)/3.14=207.07 volts

what's the meaning of the negative going half cycle in the circuit containing a bulb and a switch in series with a input ac source. i mean what happens in the -ve cycle. the dir. of current changes or any other thing. if dir. changes then why we use fuse in only phase wire.
