About electrostatics, electric fields and capacitance notes
GoConqr OriginalElectrostatics, electric fields and capacitance notes
These notes offer different ways into the unit. Static Electricity: Electric Charge introduces charge and its unit, while Static Electricity: Gold Leaf Electroscope describes an instrument used to study charge. Other notes cover point discharge, electric fields and capacitors.
How to use the notes
For an introduction, start with Static Electricity: Electric Charge, then read the notes on electrical charges and static electricity for examples of attraction and repulsion. To focus on forces, move to Static Electricity: Coulomb's Law. For fields and stored charge, explore Static Electricity: Electric Fields and Electricity - Capacitors.
As you read, write down the terms and relationships you want to remember. If you want to check your understanding, switch to a quiz on the unit page. Mind maps and flashcards there offer other ways to revisit a topic. Pick a note that matches what you are revising.
Frequently asked questions
Which note is a good place to start?
Static Electricity: Electric Charge is a useful starting point for charge and its unit. The notes on electrical charges and static electricity also give examples of attraction and repulsion. From there, you can look at notes on fields or capacitors, depending on what you are revising.
Are the notes free to use?
Yes. Every note listed here is free to open and study without an account. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes. The resources were made by GoConqr users, rather than by GoConqr.
What topics do the notes cover?
The list includes notes on static electricity, electric charge, point discharge, electric fields and capacitors. There are also notes on Coulomb's law and on the uses and dangers of static electricity. The selection spans secondary and university levels, so the detail varies between resources.
