The power equations P = VI = I^2 R = V^2 / R work for dc signals and
ac sine signals if we use RMS values (peak / root2).
Now what if we have different shapes signals? Square wave is
obvious. What about triangle wave?
Is there something like RMS that can be used for different shapes of
signals?
There are no jobs , ways to earn money , using this math .
You must actually have your hands on the circuit , and measure the
signals and
measure the outputs , to imagine how it works , then you can get a
job .
As you measure , you must imagine how the components function ,
based
on difference between inputs and the outs .
Those truely clever , will add the tiniest cap or resistor and vu
the output .
This load may be so large as to stop the circuit .
As i learned at B.B. Research in 1976 . I then asked the
Techtronics man
to sell me the cheaper scope probe ( P6006 , better , lower
loading , 7 pf) , til he could start
selling higher impedance probes ( 5000 ohm ) .
