Faraday's law : voltage not current #152

Open JohnDenker opened 8 years ago

JohnDenker commented 8 years ago

In sections 29.1 and 29.2 on pages 760 and 762 the "conceptual" statement of Faraday's law is inconsistent with the "quantitative" statement in section 29.5 on page 771. The former talks about current while the latter talks about voltage.

Suggestion:

In section 29.2, replace all the galvanometers with voltmeters. Replace every mention of current with voltage.

Rationale: There is nothing to lose by doing this, and much to gain. For starters, the voltage version applies to _all_ loops including non-conducting loops, superconducting loops, and even imaginary loops. In contrast:
