Question

need help finding all the unknows in the figure

Assuming R = 28k ohms

The image depicts an operational amplifier (op-amp) circuit. Below is a detailed explanation of the circuit components: 1. **Op-Amp Symbol:** - The op-amp is represented by a triangle with two input terminals and one output terminal. It is powered by a positive supply voltage (+15 V) and a negative supply voltage (-15 V). 2. **Input Voltage Source:** - The left side of the circuit shows a voltage source providing 2.5 V. 3. **Input Resistor:** - Connected to the voltage source is a resistor with a resistance of 10 kΩ. 4. **Inverting and Non-Inverting Inputs:** - The inverting input (`v_n`) is marked with a minus sign (-). - The non-inverting input (`v_p`) is marked with a plus sign (+). 5. **Feedback Resistor (R):** - There is a resistor labeled `R` connected from the output to the inverting input, providing feedback to the circuit. 6. **Output Voltage:** - The output voltage is labeled `v_o`, and it is connected to a load with resistance ≤ 3.5 kΩ. 7. **Current (`i_n`):** - The current flowing through the feedback resistor is labeled `i_n`. This circuit likely functions as a basic amplifier or another linear circuit configuration, utilizing the op-amp's high gain characteristics and feedback mechanisms.
