This resource turns exponential charging into a complete, ready to use review for Grade 9-12 AP Physics, covering the same idea from three different angles.

Among the ninety questions, students will see prompts such as "What is the voltage across a capacitor after 4 time constants during charging?", "What is the time constant τ for an RC circuit with R = 4 kΩ and C = 10 µF?", and "What is the relationship between the current and voltage during discharging?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 27 pages in total

Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.

Ways to Use This Resource

• Warm up review before a problem solving session
• First look diagnostic to plan your unit
• Homework or review before an exam style test
• No prep cover lesson for a substitute teacher
• Self checking practice, since every answer key includes explanations

This set is part of a complete AP Physics unit. The unit also covers Electric Current and Charge Flow, Kirchhoff’s Junction and Loop, Ohm’s Law V = IR, RC Circuit Basics, Series and Parallel Resistor, and Advanced Circuit Solving, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.

Suitable for Grade 9-12 AP Physics classes, and for review at any point in the school year.
