Assertion : Most amplifiers use common emitter circuit configuration. Reason : Input resistance to common emitter amplifier is comparatively higher.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Typically: \(R_{i}=2 \mathrm{k} \Omega, R_{0}=50 \mathrm{k} \Omega\), \(A_{I}=100, A_{V}=600\) The common emitter circuit is preferred for amplifiers as it offers both current and voltage gains, resulting in higher power gain than common-base amplifiers. Its relatively higher input resistance, comparable to the load resistance. So correct option is (1).
