ERP BJT SIGN!
I made a sign for the ERP lab to help with troubleshooting BJT transistors!
Transistors can be hard to remember, but easy to troubleshoot IF you know where to look. Now if you forget you have a neato sign to help remember. Has a picture of it being used in a basic circuit, where the voltage drops should and shouldn’t be, and its cardboard so if you bang your head on it it won’t hurt.
