Question

What is difference between ideal and practical current source?

Answer 1

Answer:

Ideal and practical current source:

The ideal current source is supposed to have infinite internal resistance, R_{s}. Again it is not practically possible to make one. Practical Current Source has some internal resistance connected in parallel to Ideal Current Source.

Answer 2

Explanation:

Ideal current --

An imaginary current source, which provides a constant current to any load ranging from zero to infinity.

Remember that the current provided is independent of voltage

. The ideal current source is supposed to have infinite internal resistance, Rs. Again it is not practically possible to make one.

practical current

Practical Current Source has some internal resistance connected in parallel to Ideal Current Source.

And some of the current flow through it and the amount of flow depends upon the load.
