Which of the following best represents an ideal current source?
Show Hint
Remember:
\[
\boxed{
\begin{aligned}
\text{Ideal Voltage Source} &\rightarrow 0\ \Omega\ \text{(series)}
\text{Ideal Current Source} &\rightarrow \infty\ \Omega\ \text{(parallel)}
\end{aligned}
}

- Zero internal resistance in parallel
- Infinite internal resistance in series
- Zero internal resistance in series
- Infinite internal resistance in parallel
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Recall the property of an ideal current source.
An ideal current source supplies constant current irrespective of the load connected across it.
Step 2: Identify its internal resistance. To ensure that the output current remains unchanged, \[ \boxed{\text{An ideal current source has infinite internal resistance.}} \] It is represented as an ideal current source in parallel with an infinite resistance. Therefore, \[ \boxed{(D)} \] is the correct answer.
Step 2: Identify its internal resistance. To ensure that the output current remains unchanged, \[ \boxed{\text{An ideal current source has infinite internal resistance.}} \] It is represented as an ideal current source in parallel with an infinite resistance. Therefore, \[ \boxed{(D)} \] is the correct answer.
