Question
**Problem Statement:** Calculate \( i_x \) and \( v_o \) in the circuit of the following figure. Find the power dissipated by the 30-k\(\Omega\) resistor. **Circuit Description:** The circuit comprises the following components: 1. **Voltage Source:** An 8 mV source is provided. 2. **Resistors:** - \(10 \, k\Omega\) connected in series with the voltage source. - \(50 \, k\Omega\) connected in parallel with the \(10 \, k\Omega\) resistor. - \(60 \, k\Omega\) connected in series with an operational amplifier denoted by an arrow. - \(4 \, k\Omega\) connected in series after the operational amplifier. - \(30 \, k\Omega\) resistor connected in series with the \(4 \, k\Omega\) resistor and linked to the output voltage \( v_o \). **Objective:** 1. Calculate the current \( i_x \) across the \(60 \, k\Omega\) resistor. 2. Determine the output voltage \( v_o \) at the \(30 \, k\Omega\) resistor. 3. Find the power dissipated by the \(30 \, k\Omega\) resistor. **Analysis:** For circuit analysis: - Apply Kirchhoff's laws or node-voltage analysis for solving \( i_x \) and \( v_o \). - Use the power formula \( P = V^2/R \) to calculate the power dissipated by the \(30\, k\Omega\) resistor. This circuit setup tests the understanding of basic electronics concepts such as Ohm's Law, Kirchhoff’s Law, and power calculations in resistor networks.
