Norton Current vs Source Voltage

Norton's Theorem

Dual of Thevenin's: any linear circuit becomes I_N in parallel with R_N.

Formulas

I_N = V_source / R1 (short-circuit current)

R_N = R1 || R2

Relation: I_N = V_th / R_th.

Example Calculation

24 V source, R1 = 1k, R2 = 2k.

  1. 01I_N = 24 / 1000 = 0.024 A (24 mA)
  2. 02R_N = 1000 x 2000 / 3000 = 666.67 ohms
