We did a hire for a first year physics instructor. One interview question we asked was:
“A student comes to you very concerned that they are expected to use current on the order of amps in the lab. They found on the internet that current much less, on order of 100 milliamps, can seriously hurt, even kill a person.”
What do you tell this student.
Surprisingly, not a single interviewee gave a suitable answer with many even seemingly lost to correctly understanding the situation. Even when prodded to the right answer, some interviewees where at a loss.
The question arises as to why? Interviewees where mostly Physics PhDs with reasonable understanding of Physics. Some even experimentalists. And yet, confounded with a very basic question of current.
