Formulas Used
Norton Current
i_n = v_source / r1Norton Resistance
r_n = r1 * r2 / (r1 + r2)Variables
| Variable | Description | Default |
|---|---|---|
v_source | Source Voltage(V) | 24 |
r1 | Series Resistance R1(Ω) | 1000 |
r2 | Parallel Resistance R2(Ω) | 2000 |
How It Works
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.
Worked Example
24 V source, R1 = 1k, R2 = 2k.
v_source = 24r1 = 1000r2 = 2000
- 01I_N = 24 / 1000 = 0.024 A (24 mA)
- 02R_N = 1000 x 2000 / 3000 = 666.67 ohms
