Youtube video, for the electrical types.

This professor is trying to confuse, bedazzle and impress rather than
teach or elucidate. Nowhere does he explain that meters connected
across the resistors are not connected to points A and D. Wires are
assumed to be of zero resistance or they would be schematically shown
as resistors, but the changing magnetic field induces a potential
difference along each wire, with total loop induced voltage said to be
1 volt. He deceptively neglected to address the relevant matter of
how this EMF was proportionally distributed in top wire, bottom wire
and the two resistors, a matter which would depend on the physical
geometry in a way left totally unaddressed in his performance.

Yes, not to mention the voltages induced in the loops connected to the
meters.

He very
briefly mentioned path of integration and showed some (incorrect)
definite integrals but nowhere did he show or speak of line
integrals.

He should be taken to the academic woodshed. He should be reprimanded,
and required to take and pass 9 credits from graduate student
instructors (for which English is a third language) in each of
political science, women's studies, elementary education for K thru 3
including a student teaching assignment, and boxing at 6 AM MWF. After
completing that penance, he should then assigned to clean the latrines
of all engineering fraternity houses for two years, and then be fired.

What do you really think? ;^)
