sorry but can anyone tell me how to convert 0.5 watts to 8 watts?
if i have a 80 watts power coming into my item...which is running at 16V and 4.3A....is it possible to power up? or is there anyway to power up my item using from a 0.5 watts source?
sorry what i am trying to say is that how to convert 0.5 watts to 80 watts which is able to sense and give the correct watts rating for the item up to 80 watts
so in this case how to convert 0.5 watts to 68.8 watts
is there anyway that i can do it by using only a 0.5 watts supply?
Thanks
If you try to power up a device that uses 80W from a power source that provides only a puny 0.5W then the power source will curl-up and die.
Have you ever tried pulling a crowded bus from your bicycle? Same thing. :lol:
Use an 80W (68.8W?) power source.

Because you provided almost no info, all I can say is memorize this formula:
Power (in watts) equals current (in amps) multiplied by voltage (obviously in volts).
P = V * I
I think the easiest way to answer your question is to connect a voltage source, a potentiometer, and an ammeter in series. Multiply the value on the ammeter by the voltage to get the power in watts. Make sure your ammeter is set to read amps, not milliamps.
that doesnt really make sense...its kinda like trying to make a power plant that is only capable of putting out 100 Megawatts to put out 200 megawatts.
for a power source to put out 80watts, it has to be capable of 80 (or more) watts
The is one nice infalible law of physics: the concervation of energy
ie what goes in MUST come out
you cannot have a power amplifier in the literal sense because that would require the spontanious creation of new energy and that is not possible (as we know it)
I have a feeling that is not what you mean and a bit more clarification is required on what you require
If such an thing wod be posible you cod run an full size electric car for miles of an 9V batery.Wich wod be cool but its imposible.
The same amount of energy that goes in comes out.Not a tini bit les or more.Some of the energy is converted in usles forms like an light bulb that is making the useful light and useles heat.If you add this up you get the same amount of energy you drove in the light bulb.
But it is posibe to covert curent and voltage.It is posibe so trun vots in to amps and the other way.
If a transformer is 100% eficent(Imposibe in realety) if you drive in 100V at 1 A you can get out 10V at 10A.

Slightly off topic, but you know we were discussing newton's law of universal gravitation today. Say you had a massive object in space and a relatively insignificant mass. Wouldn't the resultant gravitation force between the two be a violation of the laws of conservation of energy, of sorts? No input force, but yet a resultant. A super efficient system?

The small mass has potential energy relative to the large mass. Work was done through the G field to seperate them to begin with. When the small mass falls toward the large one, potential energy is converted to kinetic & heat until they collide where the remaining energy is expended in heat, light, sound etc... energy balances.
Think space shuttle. Gobs of energy expended to lift it into orbit (rockets performing work). When it comes down all of it is converted back into heat & kinetic energy coming through the atmosphere until there is very little energy remaining and it's safe to land.
quoting you styx: 'nothing is impossible, when a problem is realised the rest is just details'...
well we've realised a problem here SO let's solve it!!
just kidding anyway. unless your device would get extra energy from somewhere i don't see how that's possible.
