  1. OHM'S LAW 
    V=IR
  2. POWER EQN's
    • P =  I2 R
    • P = VI
  3. Charge 
    Q = CV
  4. CURRENT (SERIES)
    IS = I1 or I2 or I3 etc...


    (Opposite of Voltage)
  5. VOLTAGE (SERIES)
    VS = V1 + V2 + V3 etc

    (Opposite of Current)
  6. RESISTANCE (SERIES)
    RT = R1 + R2 + R3 etc

    (Opposite of Capacitance)
  7. CAPACITANCE (SERIES)
    •  1          1       
    • CT =   C1 + C2  etc...

    (Opposite of Resistance)
  8. CURRENT  (PARALEL)
    IS = I1 + I2 + I3 etc...

    (Opposite of Voltage)
  9. VOLTAGE (PARALEL)
    VS= V1 or V2 or V3 etc...

    (Opposite of Current)
  10. RESISTANCE (PARALEL)
    •  1                         
    • RT  =   R1  +   R2  +   R3 etc..
    • (Opposite of Capacitance)
  11. CAPACITANCE (PARALEL)
    CT = C1 + C2 + C3 etc...



    (Opposite of Resistance)
  12. 2 RESISTORS
    • RT  =   R1 x  R2

    •               
  13. CURRENT DIVIDER
    (OPPOSITE)

    • I1 =   IS x R2 
    •          R1+R2
    • or

    • I2 =  IS x R1 
    •         R1+R2
  14. VOLTAGE DIVIDER
    (SAME)

    • V1 =  VS x R1
    •           R1+R(equivalent)
