ENGR 44 Lab 7 "SC" Shubo C

Ideal circuit

Circuit in real life.

Test, good

Ideal cuirt

Equation to get the T in f

Equation to find Vf

Error percentage.

Conclusion: the important thing is that we do not hv Vref, so we use another power supply and resistance to do it perfectly, the idea to replace is good.
