Work Step by Step

For two or more devices connected in parallel, the voltage is the same across each device. This is Rule 1 for parallel circuits, on page 444, and discussed on pages 443-444. This is also illustrated in Figure 23.18. Each branch still feels the full power source voltage, no matter what happens to parallel branches.
