Introduction to Biasing





















Objective:
     the purpose of the lab is use the right resistance so that the LED can work normally without burning out.









conclusion: 
          Both LED works normally during the lab, the error is acceptable.  we conclude that the error was because the LEDs light are not rated correctly.

FreeMat Exercise

1. Calculation 


2. Solve by my lab:



Conclusion: I1 = -0.1857A

Introduction to DC Circuits


Introduction:
      this lab is trying to find the maximum cable length and the minimum power to load. also to find the discharge time, power to the load, and power lost







Data and analysis:




Conclusion:
     
     A submarine with power of 0.1281w can travel with up to 115.91m of AWE#30 cable provided . With 92.56% distribution efficiency,the submarine can operate for about 5 mins.
