Figure 1.19. On the left is a 12 volt battery, E1, with its positive terminal facing up. The positive end of E1 connects to the left end of R1, 330 ohms. The right end of R1 connects to the top of R2, 75 ohms. The bottom of R2 connects to the positive, right, end of a milliamp meter. The negative, left end goes to the negative, bottom, end of E1. The junction of R1 and R2 connects to the left end of R3, 100 ohms. The right end of R3 connects to the top, negative end, of E2, 6 v. The lower, positive end, of E2 connects to the positive, right end, of another milliamp meter. The left end connects to the junction of R2 and the other milliamp meter. There are semicircles with arrowheads indicating that I1 is flowing clockwise in the loop on the left and I2 is flowing clockwise in the loop on the right. End verbal description.
