Capacitors and Capacitance

Start with structure and capacitance

The Capacitors mind map introduces a capacitor as a device that stores electrical charge. It describes its structure using metal plates and an insulating dielectric. Start there if you want a picture of the components before moving on to calculations.

Next, look at the Capacitors flashcard deck. It asks for a definition of capacitance and covers the relationship C=Q/V, the unit of capacitance, stored energy and capacitor connections. Use the prompts to check what you can explain without looking at the answers.

Study discharge and stored energy

The Capacitance mind map on discharging brings together exponential charge decay and the time constant. After reading it, return to the flashcard deck and practice explaining what the time constant represents.

The Capacitors quiz includes a question about energy stored in a charged capacitor and its transfer to a motor. Try it after studying the energy material in the flashcards. If a question is difficult, use the map and cards to identify the idea you need to study again.

Use maps and quizzes together

For an initial check of related ideas, the Capacitance Pre-Knowledge Quiz includes a question about a charged balloon sticking to a wall. You can use it before the maps, then return to the concepts in the listed resources as you study.

The Physics capacitance flashcards ask about capacitance definitions, formulas and the dielectric constant. They offer another way to practice the terms and relationships alongside a mind map. The Physics Exam 2 Tophat flashcards also include questions about changes in plate area and separation.

Explore the wider unit

Capacitors and Capacitance is a section of a wider Physics unit. The listed resources connect capacitor structure and charge with stored energy and electric fields, giving you several ways to approach the section. Choose a resource and use it alongside the others as you study.
