If two identical 3 A, 4Ω Norton equivalent circuits are

Home » Network Theory » Network Elements and the Concept of Circuit » Question

If two identical 3 A, 4Ω Norton equivalent circuits are connected in parallel with like polarity, the combined Norton equivalent circuit will be—

1. 3 A, 8 Ω
2. 6 A, 8 Ω
3. 0 A, 2 Ω
4. 6 A, 2 Ω

Correct Option: D

Given,
I_N = 3A
R_N = 4Ω
When the two identical Norton equivalent circuits are connected in parallel with like polarity then I'_N = 3 + 3 = 6A
and R'_N = 4||4 = 2Ω.
