PHYS208 Fundamentals of Physics II
Answer for Ch. 28, 48P
I labeled the currents as i1 (through emf1 and R3),
i2 (through emf2 and R2), and i3 (through R1).
Why did HRW not switch the labels of R1 and R3 -- it would have made a lot more sense!
|total provided by emf1:
|total absorbed by emf2:
Note that since the current through emf2 is going in the opposite direction
to its polarity, it is being re-charged (receiving power from emf1).
