Embedded Systems — question 7 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
Low-power validation is one of the first hands-on measurement exercises an intern is likely to run.
Your board is supposed to draw under 10uA in deep sleep, but your bench measurement shows a steady 2mA instead. Walk me through how you'd track down where the current is going.
