**BJT Amplifier Analysis**

**Problem 6:**

For the BJT amplifier given below, with a \( \beta_{DC} = 200 \), perform DC analysis to calculate the emitter DC current. The tasks are:

a. Determine the voltage gain for this unloaded amplifier.

b. If a load resistance of 3300 Ohms is placed on the amplifier output, what is the voltage gain?

**Circuit Diagram:**

- **Power Supply:**
  - \( V_{CC} = +10 \text{ V} \)

- **Components:**
  - \( R_1 = 33 \text{ k}\Omega \)
  - \( R_2 = 6.8 \text{ k}\Omega \)
  - \( R_C = 3.3 \text{ k}\Omega \)
  - \( R_{E1} = 330 \text{ }\Omega \)
  - \( R_{E2} = 120 \text{ }\Omega \)

- **Capacitors:**
  - \( C_1 = 1 \mu \text{F} \)
  - \( C_2 = 10 \mu \text{F} \)
  - \( C_3 = 1 \mu \text{F} \)

- **Inputs and Outputs:**
  - \( V_{in} \) at node before \( C_1 \)
  - \( V_{out} \) after \( C_3 \)

**Description:**

The circuit is a common-emitter amplifier with a voltage divider biasing network. The supply voltage \( V_{CC} \) is 10 V. The network consists of \( R_1 \) and \( R_2 \) used for biasing, and \( R_C \), \( R_{E1} \), and \( R_{E2} \) are used for amplifier configuration.

In the provided circuit, capacitors \( C_1 \), \( C_2 \), and \( C_3 \) are coupling and bypass capacitors to ensure AC signal passage while blocking DC components. The schematic layout has \( V_{in} \) at the input side with \( C_1 \), and \( V_{out} \) on the output side with \( C_3 \).

The DC analysis will provide the emitter current necessary for calculating the voltage
