**Figure (Q1): Transistor Biasing Circuit**This diagram depicts a common emitter transistor biasing circuit, which is used to set a specific operation point for a bipolar junction transistor (BJT).**Components:**1. **Transistor (Q1):** The central component of the circuit, consisting of three terminals: - **Base (B):** The input terminal that controls the transistor's operation. - **Collector (C):** The terminal through which the main current flows. - **Emitter (E):** The terminal from which the current exits the transistor.2. **Resistors:** - **\( R_B \):** Connected to the base (B) and provides the necessary base current. - **\( R_C \):** Connected to the collector (C) and helps in dropping the collector voltage. - **\( R_E \):** Connected to the emitter (E) and stabilizes the emitter voltage.3. **Power Supplies:** - **\( +V_{CC} \):** Positive supply voltage applied to the collector. - **\( -V_{EE} \):** Negative supply voltage connected to the emitter.**Functionality:**The resistors \( R_B \), \( R_C \), and \( R_E \) are used to set the biasing conditions for the transistor. The base resistor \( R_B \) controls the base current, thus influencing the transistor's operation state. \( R_C \) drops voltage at the collector, affecting the output voltage, while \( R_E \) helps maintain stability by limiting the emitter current and providing feedback.This setup is crucial for ensuring the transistor operates efficiently in its active region, making it suitable for amplification purposes in various electronic applications. **Transcription for Educational Website:**---Let a DC current source \( I_s = 10 \, \mu A \) be connected across \( R_B \) in Figure (Q1), between node (B) and ground.
