## 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.

### Formulas
**I_N = V_source / R1** (short-circuit current)
**R_N = R1 || R2**
Relation: I_N = V_th / R_th.
计算示例
24 V source, R1 = 1k, R2 = 2k.
- I_N = 24 / 1000 = 0.024 A (24 mA)
- R_N = 1000 x 2000 / 3000 = 666.67 ohms
