Question

In case of ideal current sources, they have ___________

(a) zero internal resistance

(b) low value of voltage

(c) large value of currrent

(d) infinite internal resistance

I had been asked this question in unit test.

My question is from Voltage and Current Sources in section Circuit Elements and Kirchhoff’s Laws of Network Theory

Answer 1

Correct choice is (d) infinite internal resistance

To explain I would say: For the ideal current sources, the current is completely independent of voltage and it has infinte internal resistance.
