Linear Circuit Analysis

CircuitsU is an interactive, step-by-step, tutoring website designed to assist students in learning the basic methods and principles of analyzing electric circuits. At this time, the site focusses only on linear circuits analysis, but our goal is to also extend it to nonlinear circuits (electronics) in the future. Other topics might also be added.

Every problem in CircuitsU is generated randomly with a pre-defined level of difficulty and each student will receive a different set or problems. Students can practice solving as many problems as they want, however, in order to get the maximum score for a particular homework assignment, they need finish correctly the minimum number of problems before the deadline set by the instructor.

Instructors

Use your instructor account to create a new course/class at the beginning of each semester. Then, build the set of homework problems that you want to assign to your students or leave the default assignments that are currently set for a standard college-level Linear Circuit Analysis course. The problems that the students receive are generated randomly based on the type and level of difficulty that you select. You will be able monitor the progress and scores of each student in your class.

To enroll students in a course, you need to upload a list of email addresses (one email per student) to which CircuitsU will send automatic registration emails. The students will use this email address as their user name and, the first time when they login, they will be asked to set a password. Once the students login into their accounts, they will be able to see the homework assignments that you created for them.

Please send an email to learn.electric.circuits@gmail.com if you need an instructor account on CircuitsU. Once you have an account you can use it to create multiple classes as long as your instructor account remains active (normally, instructor accounts should never expire).

Students

If you are a new student, you need to set a password first by clicking the link in the email that the instructor sent you to give you access to his or her class. The email address is the only information that you need to have an account and will be used as your user name in CircuitsU. The email can also be used to recover the password in case you forgot it. Besides your email, you do not need to introduce any other personal information such as name, school, etc. in order to use the website.

If you cannot solve a problem, you can click the «Help», «See answer», or «Show solution» buttons, however, in the last two cases you will not receive any points for that problem and you will need to solve another problem of the same level of difficulty to receive credit. CircuitsU is specifically designed to provide feedback and help you at each step when solving a problem.
