In 2018, YouTuber ElectroBOOM and Walter Lewin feuded over the nature of this law. For 10 points each:
[10m] Name this law used in mesh circuit analysis that states that the sum of the voltage differences around a closed loop is zero.
ANSWER: Kirchhoff’s voltage law [or Kirchhoff’s second rule or Kirchhoff’s loop rule; prompt on Kirchhoff’s law or Kirchhoff’s rule or loop rule]
[10e] ElectroBOOM criticized Lewin’s experiment that claimed to show that Kirchhoff’s voltage law does not hold in the presence of one of these fields that feature north and south poles.
ANSWER: magnetic fields [or B fields]
[10h] ElectroBOOM claimed that Lewin’s results were due to incorrect use of oscilloscopes, which plot waveforms that are read by these units, the distances between grid lines. The scale of an oscilloscope screen is given in time per these units versus volts per these units.
ANSWER: divisions [or divs]
