Transcribed Image Text:**Figure P5.6 Analysis**
5.6 Find \( i_L \) (in milliamperes) in the circuit in Fig. P5.6.
- **Figure P5.6 Description**: The circuit contains an op-amp with a feedback loop. Key components are:
- An 8 kΩ resistor connected to the inverting input (\(-\)) of the op-amp.
- A 240 mV voltage source connected in parallel with the 8 kΩ resistor.
- A 40 kΩ feedback resistor from the op-amp output back to its inverting input.
- A 20 kΩ load resistor connected from the op-amp output to ground.
- A 15 V power supply is connected to the op-amp.
The task is to calculate the current \( i_L \) flowing through the 20 kΩ load resistor.

**Figure P5.7 Analysis**
5.7 A voltmeter with a full-scale reading of 10 V is used to measure the output voltage in the circuit in Fig. P5.7. What is the reading of the voltmeter? Assume the op amp is ideal.
- **Figure P5.7 Description**: This circuit also contains an op-amp with a voltage supply.
- A 3.3 MΩ resistor and a 9 V battery are connected in series to the non-inverting input (\(+\)) of the op-amp.
- The op-amp output is connected through a feedback loop with the non-inverting input.
- The task is to determine the voltmeter reading when connected across the op-amp output with an ideal op-amp assumption.
This configuration requires analyzing the feedback loop to determine the output voltage given the input voltage and resistances.
