9. ### making a word file from a text

checkout this link hope it will give you complete guidance.... ;-) Demo https://chemistry.stackexchange.com/questions/2509/how-do-i-type-a-simple-chemical-equation-in-microsoft-word
10. ### Three Phase Current Calculation

Vline = ((3)^1/2)*Vphase Iline = Iphase =10amps each phase draws the same current according to the above relation. You have to use circuit breaker of rating 10amps.

I think your load resistance should be changed(deccreased) in order to draw more current from the supply.
12. ### Potential Difference between Charger and Battery

thank you bill6656 & tpetar... now i m not confuse... ;)
13. ### PC 12V fan and neagtive voltage

I think loop is not completed via ground in case of DC current. In Transmission systems the return path is the neutral i (for AC) and the -ve terminal (for DC).we cannot say it as ground technically. Current will always flow from the higher potential difference to the lower potential...
14. ### Potential Difference between Charger and Battery

Yes I explained my question added further lines not change the question. There is no "universal equation" that will answer your question, as it varies with battery chemistry (LedAcid, NiCd, NiMH, LiIo, LiPo, ...) i just want to know equation nothing else if it exist.As u said it is not. its...
15. ### Potential Difference between Charger and Battery

I'd not change my question but only explained further
16. ### why in fourier transform we have to multiple with e^{-j\omegat}

Re: why in fourier transform we have to multiple with e^{-j\omega t} The sinusoidal time function that a phasor represents is obtained by multiplying the phasor by e^ jwt
17. ### Potential Difference between Charger and Battery

Charger Voltage should be how much greater than that of battery...!!!!! any (x)battery, any (?)charger... charger voltage>how much of battery voltage. I'm not asking about particularly of car battery. I am talking about general concept of battery and charger
18. ### Potential Difference between Charger and Battery

I was asking as general. car battery was an example to explain my question. Charger Voltage should be how much greater than that of battery. any formula or concept to explain this
19. ### operation of zener diode in this circuit

I think the only need of zener in that particular point is dissipation because for switching purpose single Diode is enough.
20. ### Need help on a project....

Yes, input voltage must be between 7V and 20V and the output voltage is between 4.75V – 5.25V . Connect a diode 1N4007 on the input in order to block the flow of current by discharge of capacitor.See this
