Answer / velthe chipmaker
Give the 10v ac to primary of the transformer . (input of
the transformer is 10v &out is 15v by using the step up
transformer)
it will give pulsetting dc, (pulsetting dc means dc power
with some ac componant).
then the pulsetting dc is given to the full wave rectifier .
rectified output is abow 10v so voltage regulater is used to
produce 1oV dc supply.

Answer / raj
first use the voltage doubler for twise the voltage and
give to the full wave rectifier and then pass through
filter to get the 10 volt dc

Answer / sachin
First give the sine wave to a full wave rectifier followed
by a filter to get 10v dc output. Use this dc voltage as
supply voltage for a 555 timer used as an astable
multivibrator.The output square wave is then given to the
following ckt to produce the reqd. -ve voltage.

Answer / sathi
first apply the sine wave to a full wave rectifier to get +10v dc
then apply this to a inverting op-amp amplifier to get -10v dc

Answer / sindu
very easy use two 7810
___IC 7810 ___ ____1st pin______2nd pin_____________3rd pin
___1st one ________12 volt AC___Gnd________________10volt o/p
___2nd one ________12 volt AC___Gnd from 1st one___-10volt o/p
in this manner we get -10volt dc

Answer / joby sekhar
10 V peak to peak sine wave sent through full wave bridge
rectifier and use PIE filter for getting pure DC and give
grounding to positive supply ,you will get -10V DC.

Answer / prasant choudhury
first apply it to a comparator ( or astble multivibrator) with saturation voltage 10v and vref as ov. Then apply the output to the full wave rectifier (so as to produce -ve dc voltage ... easy).
