Q) Since VDD=+15 V, VTH= +2 V and K= 100mA/V^2 in the circuit below, what is the ID current?  (R value specified in resistors in the circuit is ohm expression)                                                                                                                           NOT : I found the value of the current Id and it was 16 m A , but it was not there in the options, so I want to know what the correct answer is, although the options contain the voltage and required in the current question. Is there an error, and if the error is present, I want to answer the question  to know what is required. please

### Electronic Circuit Analysis #### Circuit Description: The given diagram is a common-source FET (Field-Effect Transistor) amplifier circuit. The essential components and their values are labeled in the following way: 1. **Power Supply and Input/Output Voltages:** - \( V_{DD} = 15V \) - \( V_{in} \): Input Voltage - \( V_{out} \): Output Voltage 2. **Passive Components and Their Values:** - \( R_1 = 200k\Omega \) - \( R_2 = 100k\Omega \) - \( R_3 = 150\Omega \) - \( R_D = 470\Omega \) - \( C_1 = 0.12\mu F \) - \( C_2 = 0.12\mu F \) #### Explanation of Components and Their Interconnections: - **Resistors \( R_1 \) and \( R_2 \):** These resistors form a voltage divider network to provide the necessary gate bias voltage for the FET. - **Capacitor \( C_1 \):** Placed between the input voltage \( V_{in} \) and the gate of the FET, it acts as a coupling capacitor, allowing AC signals to pass while blocking DC components. - **Resistor \( R_D \):** Connected to the Drain of the FET, it loads the amplifier and helps to set the output voltage \( V_{out} \). - **Capacitor \( C_2 \):** Connected to the output, it couples the amplified signal to the next stage or to the output load, blocking any DC offset. - **Resistor \( R_3 \):** This resistor is connected to the source of the FET and provides stabilization in the circuit by establishing a reference voltage. #### Calculations and Analysis: To determine an unknown voltage within the circuit, the provided values must be inserted into the corresponding equations for a common-source amplifier. The exact value required amongst the given options (5.1V, 1.28V, 2.55V, 10.2V) would be attained through detailed circuit analysis and solving. #### Multiple Choice: Which of the following is a probable calculated value in this circuit? a) 5.1 V b) 1.28
