## Which load meets a 3.20 V minimum?

Ideal model: a 5 V source, 1 kΩ upper resistor and 2 kΩ lower resistor. The external load is parallel to the lower resistor. Ignore tolerances for this exercise.

### Three candidate loads

| External load | Predicted output | Requirement |
| --- | --- | --- |
| 2 kΩ | 2.500000 V | At least 3.20 V |
| 10 kΩ | 3.125000 V | At least 3.20 V |
| 20 kΩ | 3.225806 V | At least 3.20 V |

## Your turn

Which candidate passes? Calculate the ideal load resistance at the exact 3.20 V boundary.

## Your answer

[Write your approach here.]

## For your own application

Add the 16 kΩ boundary case to the calculation and distinguish exact model compliance from a practical design margin.
