Linear Circuit Analysis

CircuitsU is a free, interactive, step-by-step, tutoring website designed to assist people in learning the basic methods of analyzing electric circuits. The site focusses on linear circuits, but other topics such as electronics (nonlinear circuits) and more advance design problems will be added in the future.

  • Instructors – use CircuitsU in teaching linear circuits and/or give online homework assignments, midterm or final exams to your students. The website is designed to be self-sufficient and does not require to use other materials or textbooks.
  • Students – solve your homework problems online and practice additional problems if you want
  • Others – learn how to analyze electric circuits by reviewing and solving the practice problems at the end of each chapter of the Webbook.

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 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, 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 access the class. Your email address represents your user name and can be used to recover the password if necessary. Besides your email, you do not need to provide any other personal information such as name, school, etc. in order to use the website.

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

Others

If you are a returning student or if you are simplly interested in learning about electric circuits, technics to analyzing them, or simply want to test your skills in linear circuits, you can solve the randomly generated problems at the end of each chapter in the Webbook. You do not need an account to browse the Webbook, however you need to login to review and solve problems.
