    OPTOCOUPLERS

    hello everybody! as audioguru said in his last post that optocouplers prevent expensive devices like computers from burning out.but there is one thing that if we have high voltage across say a motor winding with respect to ground and we still short the two grounds of computer and motor what...

    OPTOCOUPLERS

    hi audioguru! u gave the example of a triac controlled lamp earlier.  GROUND IS A GROUND I.E ZERO WITH RESPECT  TO LIVE NOW WHETHER IT IS COMPUTER'S 5 V GROUND  OR AC 230V GROUND WHAT DIFFERENCE DOES IT MAKE? WHAT "BAD" CAN BE CAUSED BY SHORTING 2 ZERO POTENTIAL POINTS? WHICH MAKES U SAY...

    741 op amp

    hi audioguru! wat do u wish to say by writing that some opamps use -ve supply as ground what does this imply? prateek

    741 op amp

    hi all! u all might be knowing 741 ic is an operational amplifier. it is an 8 pin IC.AND WE ALSO KNOW THAT 8th pin is not used and it is neither ground. i sometimes wonder why do manufacturers include this pin,i.e there is no need to take this connection 7 pin wont be sufficient? comments? prateek

    multiplier

    hi mony! there are many ways of building voltage multipliers ! one of them is by using capacitors principle of storing charge ie by using RC networks  in cascade .can also be made by using  full adders(specifically for multiplying 2 numbers) prateek

    How to TEST this beast?

    hi audioguru! i think that is where his misery lies,even if his meter has a diode switch or even if it has resistance switch,i think multimeter battery will not be strong enough to circulate ample current through 44k resiatance!! an external source may be required prateek

    How to TEST this beast?

    IN MY OPINION THE CONVENTIONAL CONTINUITY CHECK IS DIFFICULT HERE MAY BE IF YOU HAVE EXTRA STOCK!!!!!TRY  CAN GO FOR IT OUT APPLYING SOMEWHAT HIGHER VOLTAGE B/W BASE AND EMMITER.OR U CAN MEASURE THE DEVICE GAIN BY CONNECTING SUPPLY AND A few VOLT SIGNAL(mV SIGNAL WILL I GUESS BE INSUFFICIENT TO...

    Want DIGITAL VOLT METER for AC

    hi there! feed a rectified AC to ur meter first use 10 different AC VALUES then calibrate your meter for corresponding DC value prateek

    FM WAVE PROPAGATION

    hi audioguru! i think in my case i connected electrolytic capacitor with correct polarity but internally the polarity was reversed. i.e i put the blame on the capacitor manufacturer.is it fair enough as an explanation? how often is it the case? prateek

    FM WAVE PROPAGATION

    AND I MUST CONFESS I HAVE SEEN A VERY HIGH VOLTAGE CAPACITOR EXPLODE! IT IS ALMOST LIKE A BOMB WHICH CAN EVEN KILL.THE YELLOWISH PASTE COMES OUT WHICH IS REALLY HOT!!!!! PRATEEK

    OPTOCOUPLERS

    hi audioguru! my question still remains.what are these optocouplers.i only know one line pertaining to them "they have same relation to 2 ground points isolated from each other"which i could search from google.com reply soon prateek

    FM WAVE PROPAGATION

    audioguru! though in any case i have only seen electrolytics caps exploding ceramic capacitors just turn blackish if i apply high voltage across them prateek
