Question

What is the approximate gain (Vout/Vin) for the circuit shown in Figure 5-67?

**Figure 5-67 (Exercise 5-16)**

This diagram depicts a simple transistor amplifier circuit. Here is a detailed breakdown:

- **Power Supply**: The circuit is powered by a +12 V source.

- **Resistor**: A 3 KΩ resistor is connected in series with the 12 V supply, and it guides a current of 1 mA flowing through the circuit.

- **Transistor**: The transistor is a key component in the circuit, with three terminals:
  - The left terminal is the base, where the input voltage \( v_{in} \) is applied.
  - The top terminal is the collector, connected to the 3 KΩ resistor.
  - The bottom terminal is the emitter, grounded.

- **Output Voltage (\( v_{out} \))**: The output voltage is taken from the junction between the resistor and the collector of the transistor.

This circuit typically amplifies the input signal (\( v_{in} \)) applied at the base of the transistor, resulting in a corresponding output signal (\( v_{out} \)).
