Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Series vs. Parallel Circuits - Questions 10 Help

Wiring two or more devices together in a circuit can be done in a variety of ways. The two most common ways are to wire the devices in a series circuit or as a parallel circuit. Whether the devices are in a series or a parallel arrangement affects the properties that the circuit would exhibit.

There are two similar versions of this question. Here is one of the versions:

Version 1:

When the circuit is turned on, all of my light bulbs will seem to light at the same time.

Series Circuits are characterized by a single pathway from the + to the - terminal of the battery. The bulbs are arranged in a consecutive fashion such that any charge that passes through the first bulb will also have to pass through the second and the third bulb. Charge is conceived as circulating through the circuit together. If a wire is disconnected anywhere in the circuit, all bulbs will be affected and will be unlit.

Parallel circuits are quite different because the bulbs are all placed in an individual branch with each branch operating independent of the others. The current in a branch is not affected by anything that is present in the other branches. A disconnection or a burned out bulb within a branch has an impact that is confined to that branch. However, a disconnection that occurs outside of the branch will have an affect upon all the branches since it opens the entire circuit and not just a part (i.e., a branch).
