**Determine the power consumed by the 1kΩ load.** The diagram shown is an electronic circuit that includes the following components: 1. **Current Sources:** - A 10 mA current source is connected to a 1 kΩ resistor on the left side of the circuit. - A 50 mA current source is positioned below it, also feeding into the circuit. 2. **Resistors:** - A 1 kΩ resistor is connected in series with the 10 mA current source. - A 100 Ω resistor is connected at the input of an operational amplifier. - Another 1 kΩ resistor is connected to the inverting input of the operational amplifier. - At the output, a 1 kΩ resistor is in series, connected to where \( V_{\text{out}} \) is measured. 3. **Operational Amplifier:** - The op-amp has a non-inverting terminal receiving input directly from a node connected to the 50 mA source. - The inverting input is connected through two resistors: one 100 Ω resistor from the 50 mA node, and another 1 kΩ resistor in series. 4. **Output:** - The output voltage, labeled \( V_{\text{out}} \), is across the 1 kΩ resistor on the far right. **Objective:** - Calculate the power consumed by the 1 kΩ resistor connected to \( V_{\text{out}} \). The power consumed by a resistor is calculated using the formula \( P = V^2 / R \), where \( P \) is the power, \( V \) is the voltage across the resistor, and \( R \) is the resistance (1 kΩ in this case).
