95 watts is equal to how many volts??
 

Re: watts conversion???

P=VI
Watts are volts * current!
It is a measure of power, voltage is a measure of potential difference.

That is akin to aking how many litres are equal to 1 meter.

Dont mix oranges and apples... Not the same thing...
 

Re: watts conversion???

can sum one tell me how the conversion is possible instead of arguing out there???
 

    V

Re: watts conversion???

Well,
P=V*I=V²/R=I²*R
So Voltage:
V=P/I=√(R*P)
 

Re: watts conversion???

Sure if you tell me how to convert copper to gold...
Look, you cannot convert watt to volt, they are completly separate units.

1W=1J/1s=(1kg*1m^2)/(1s^3)=(1N*1m)/(1s)
1V=1J/1C=(1N*1m)/(1A*1s)


As you can see 1W is not equal to 1V...

If you know current or resistance you can calculate (not convert) voltage from power...
P=V*I=V^2/R=I^2*R

You can convert watts to hors power, because they are power units. You can convert miles to metres, galons to litres, unces to kilogramms, but not watt to volt...
 

Re: watts conversion???

MY bad i'll frame the question pproperly...............
an AMD ATHLON DUAL CORE processor consumes 95 watts of power, so what is the voltage
 

Re: watts conversion???

Oh, ok, well this is totaly difrent thing. Well not sure but i think that the core voltage of processor is around 1.3V. Has nothing to do with power. Voltage is constant here, not the power. Power may varie depending what you do.

It just means that your core current is :
I=P/V=95W/1.3V=73A

Click to expand...

Power consumption in a processor is down to many things, operating voltage being one of them. The switching speed (frequency of operation) etc all contribute to the current.

Power = Voltage x Current.

Oh, and I'm not arguing - I'm just answering your question.
 

Re: watts conversion???

Also the power requirements of a CPU is typically the maximum current that the chip can handle. As mentioned power requirements are a function of several factors not least being the resistance since heat affects resistance and resistance affects the current the power of the CPU is also a factor of the ambient / die temperature.

However - you cannot convert Watts into volts, amperes, ohms etc. What you can achieve is to determine the current required to produce a specific power level given the voltage / resistance and that type of thing.
