Systems and Control Electronics

1. Kirchoff's Laws

   • Current
     • All current into a node = current out
   • Voltage
     • All voltage supplied = all voltage used

2. Resistors

   • In series
     • Rt = R1+R2+R3
     • All the restores add up
   • In parallel
     • 1/Rt = 1/R1+1/R2+1/R3

3. Potential dividers

   • Vout = Rbottom/Rbottom + Rtop x Vin

4. Transistors

   • Ic = Gain x Ib
