my device (circuit simulator) will result 45w where voltage and current of the energy source are amplified , but remember my device consist of LM741 op-amps and DC power amplifier which needs s external power supplies in order to operate..LM741 needs an external power supply of positive and negative 15 volts, and the DC power amplifier needs an external power supply of positive and negative 24 volts to operate... Of course my device consumes power in order to operate but it produces a a magnified voltage versus current curve that is simillar to the curve of the small energy source with a small voltage and current.
If you still have doubts let me know please.... Thanks a lot for your reply and support....
