Me and my lab partner recently completed a lab experiment dealing with transistor data and "the collector characteristic curve for the CE connection". We completed the experiment on our actual workbench and on an electronic circuit simulation program (Multi-Sim). The results on Multi-Sim were twice as much as our actual results. For example 13.582 mA on Multi-Sim was 6.53 mA for our actual results; but both were the same circuits. Any reasons of why this may be happening or troubleshooting ideas are greatly appreciated.

I'd need to see the circuit and your calculations, but my guess is that the actual HFE of the transistor was not the same as on the simulator. HFE can vary over a wide range. Or perhaps you misread the value of one of the resistors. Or one was damaged.

It's easy enough to look at the circuit and calculate the IC. did you do that?

you can email me with more details.
