Lab Instrumentation — question 4 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.

You need to measure the voltage across the high-side switch of an isolated flyback converter using two single-ended scope probes, both referenced to earth ground through the scope chassis. What goes wrong when you connect the second probe's ground clip, and what should you do instead?

How sure are you?

Being confidently wrong costs more mastery than admitting a guess — that is deliberate, and it is how misconceptions get found.

Neither is graded, and nothing here is recorded.
