किसी उभयनिष्ठ उत्सर्जक ट्रांजिस्टर प्रवर्धक में, संग्राहक के सिरों के बीच श्रव्य-संकेत वोल्टता \(3\, V\) है। संग्राहक का प्रतिरोध \(3\, k \Omega\) है। यदि धारा-लल्धि \(100\) तथा आधार का प्रतिरोध \(2 \,k \Omega\) है तो, प्रवर्धक की वोल्टता-लब्धि तथा शक्ति-लब्धि के मान क्रमश: होंगे :

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
