## Resistance Ranking Tasks - Questions

The Resistance Ranking Tasks Concept Builder is comprised of 36 questions. The questions are divided into 12 different Question Groups. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three different activities in the Concept Builder. Those three activities are differentiated as follows:

• Resistance and Length: Question Groups 1-3 Three Question Groups, with each question requiring the learner to rank the relative resistance of three wires of varying length.
• Resistance and Area: Question Groups 4-6 Three Question Groups, with each question requiring the learner to rank the relative resistance of three wires of varying cross-sectional area.
• Putting It All Together: Question Groups7-12 Six Question Groups, with four Question Groups requiring the learner to rank the relative resistance of three wires with different length and different cross-sectional area.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes. We recommend all three activities. The first two activities are short and can be done quite quickly. They provide excellent preparation for the more challenging third activity.

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
