Hi,
I have a few breadboards with many IC's - analog and digital. How can I estimate the total power consumption? I know P = IV = I^2/R. Is it just my overall supplied source * total current consumption?
I'm currently supplying my breadboards with a single power source, and using voltage regulators to knock the voltage levels down. (I'm given a source > 20V. I'm using +15, +5 regulators to power my ICs). I see that the oscilloscope sources approximately 500 mA of current.
Thanks.
