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.

Mission EC7 Series Circuits Concepts

Mission EC7 pertains to series circuit concepts. A large number of the questions will probe your understanding of how a change in one variable (e.g., the number of resistors, the resistance of a resistor, the battery voltage, etc.) will affect other variables (e.g, the current in a circuit, the current in a resistor, the overall resistance, the voltage drop across a resistor, etc.). The mission consists of 40 questions organized into 10 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...

Learning Outcomes

  • The student should be able to identify a series circuit if given a circuit diagram, to identify the effect of an increasing number of resistors in series upon the equivalent resistance, and to determine the equivalent resistance of a series circuit if given individual resistance values.
  • The student should be able to identify the effect of varying the number of resistors, varying resistance, and varying battery voltage upon the total circuit current and the bulb brightness of a series circuit.
  • The student should be able to compare the voltage drop across resistors in a series circuit and be able to identify the effect of increasing number of resistors upon the voltage drop across an individual resistor in a series circuit.
