- \(16 \text{ A}\)
- \(12 \text{ A}\)
- \(24 \text{ A}\)
- \(30 \text{ A}\)
- \(4 \text{ A}\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Maximum current occurs when external resistance \(R = 0\) (short circuit).
Step 2: Detailed Explanation:
\(I_{\text{max}} = \frac{E}{r} = \frac{12}{0.5} = 24 \text{ A}\)
Step 3: Final Answer:
Maximum current = \(24 \text{ A}\).
Maximum current occurs when external resistance \(R = 0\) (short circuit).
Step 2: Detailed Explanation:
\(I_{\text{max}} = \frac{E}{r} = \frac{12}{0.5} = 24 \text{ A}\)
Step 3: Final Answer:
Maximum current = \(24 \text{ A}\).
