EMF Pt. 2 of 2
Professor Nathaniel H. Frank of Massachusetts Institute of Technology
Lecture film. Measuring joules needed for 24 division deflection of thermocouple meter. Weights dropped & energy dissipation measured. Heating element connected to switch & battery. Heating element then put between copper cylinders to measure the deflection. Resistors shown & explained. Electromotive Force of battery explained. EMF measures chemical energy stored in battery & measures amount stored. “Any such device which supplies energy w/ help of electric charges is considered a seat of EMF though EMF is not stored.”
02:56:25 Bicycle attached to a generator to generate energy (that isn’t stored at all) but EMF is measured.
