Simple led query.
The current should not have changed. What does the community members think. It should have remained 40mA itself but with the led the current shown is 21mA. Is this correct. Please advise.

Hello friends, I just wanted to know if the current shown in led circuit is correct. I feel it should have been 40mA for 6v and 150r resistance. But here it shows some different value. Seems like the software is not evaluating correctly when a led is connected

Am I missing something in my concept?

6v / 160 = 40 mA. 6V - 2.75 / 21.6 mA. You forgot to take the 2.75V Led Voltage into consideration.
