Norton Current vs Source Voltage
公式
## 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.
计算示例
24 V source, R1 = 1k, R2 = 2k.
- 01I_N = 24 / 1000 = 0.024 A (24 mA)
- 02R_N = 1000 x 2000 / 3000 = 666.67 ohms
常见问题
Norton vs. Thevenin?
Thevenin: voltage source in series with R. Norton: current source in parallel with R. They are duals.
How to convert?
I_N = V_th / R_th. R_N = R_th.
When to use Norton?
When the load is in parallel with the source; otherwise either works.
