## Thevenin's Theorem
Any linear circuit can be replaced by V_th in series with R_th.
### Formulas
**V_th = V_s x R2 / (R1 + R2)**
**R_th = R1 || R2 = R1 x R2 / (R1 + R2)**
Any linear circuit can be replaced by V_th in series with R_th.
### Formulas
**V_th = V_s x R2 / (R1 + R2)**
**R_th = R1 || R2 = R1 x R2 / (R1 + R2)**
计算示例
24 V source, R1 = 1k, R2 = 2k.
- V_th = 24 x 2000 / 3000 = 16.0 V
- R_th = 1000 x 2000 / 3000 = 666.67 ohms
