In Fig. 27-54, the resistances are R j = 1.0 nand R2 = 2.0

Chapter 27, Problem 45

(choose chapter or problem)

In Fig. 27-54, the resistances are R j = 1.0 nand R2 = 2.0 n, and the ideal batteries have emfs 'is [ = 2.0 V and 'iS 2 = 'iS 3 = 4.0 V. What are the (a) size and (b) direction (up or down) of the current in battery 1, the (c) size and (d) direction of the current in battery 2, and the (e) size and (f) direction of the current in battery 3? (g) What is the potential difference Va - Vb?
