Topic: Analog Circuits
A linear regulator is attempted using discrete components as shown below. What is the output voltage?
(The circuit shows a 10 V supply, an NPN transistor, a 2.5 V source at the base, and resistors. Output $V_o$ is measured across the load.)
- A. 9.3 V
- B. 7.5 V
- C. 0 V
- D. 2.5 V
Answer: A. 9.3 V
Explanation: Based on the official answer key, the correct option is (a). No detailed mathematical derivation is provided in the reference.
