Re: Personal Problem to Link OpAmp with SubCircuit


 

Hello,

Thank You very much, Helmut. Your help was helpful! I now can use the TL071-OpAmp in my circuits - perfect.

But one thing astonished me:
As I changed the value of a resistor, I saw that it is possible to give the "power rating" of the resistor. So I tried it and gave the resistor a power rating of 0.25 Watt. Then I simulated the circuit and "burned" my resistor with a power of 1.5 Watt. That was possible without a problem. Instead I expected an error message by LTSpice like "The resistor R1 was driven by 1.5 Watt instead of 0.25 Watt and is now smoking". So what serves the power rating for? And how can I use it?

Yours,

Bernhard
