Hi mhackgyver,

The .ic tags look like sources but really are Inital condition setings.
Used in the monovibrator to help the sim simulate an oscilator.
also used to precharge the cap in the selfrunning sim circuit.

Hi Dr. Spark,
at the scopeshot:
3fett1_10ohma.jpg

you get about (4 Volts)^2 / 10 Ohms= 1.6 Watts of output power.

But what was the input power at R1 in this case ?

Many thanks.
Regards, Stefan.

I've build that:



and the result:

R1:


how that can be possible after the diode?


R2:

@mhackgyver

probably your diode does not work anymore.
YOu have about 0.12 Ampere average input current, thus at 10 Volts
1.2 Watts input.
Your output at R2 is about (3.5 Volts)^2 / 10 Ohms= 1.225 Watts,
so the graphical interpolation could be a bit less or more, so
it seems what you put in is also
coming out at R2, so this is right.

Hmm,
what I just wrote is not right...
Where exactly is the zero line of the input voltage at R1 ?

If it is in the center of the square waveform,
then when the current is negative,
we could have a charging of the battery,
if the other multivibrator circuit is not broken...
Strange,
please check the diode and the rest of the circuit.
Thanks.
