Electrical Fundamental

1. OHM`LAW

   • V=IR
   • P=VI
   • P=V^2/R

2. Kirchoff`s LAW

   • Current in = Current out
   • Voltage in = Voltage out

3. Thevenin`s Theorem

   • Find Rth
     • Find Vth
       • Ith=Vth/Rth

4. The Super Position Theorem

   • Calculate the current with the first volatge
     • Calculate the current with the second voltage
       • Add togther if the current same direction
