SUMMARY
The discussion focuses on determining the electromotive force (EMF) of a battery using two voltmeters with different readings. When connected individually, the voltmeters read V1 = 0.9V and V2 = 0.6V, while connected simultaneously, they read V3 = 0.45V. The equations derived from the readings include V1 = E - I1R1, V2 = E - I2R2, and V3 = E - I3R3, where I1, I2, and I3 are the currents through the respective voltmeters, and R1, R2, and RB are their resistances. The discussion emphasizes the importance of understanding the differences between ideal and real voltmeters and batteries in calculating the EMF accurately.
