Silicon Validation Intern
Write a real answer. It is graded against the question's stored rubric, the mastery movement is computed by the same engine the product uses, and — the part worth watching — the next question is chosen by the real scheduler from what you have already answered. Nothing is saved.
One difference worth stating plainly: scoring here is deterministic rather than model-written, so this page costs nothing to run and cannot be used to burn anyone else's tokens. In a real track the same rubric is graded by the model, which is what produces feedback about your specific reasoning rather than about coverage.
Bench supply set to 12 V with a 500 mA current limit. The board should draw about 150 mA at idle.
You power a brand-new board for the first time and current draw immediately hits the supply's limit. Walk me through how you would debug it.
