About electric circuits and current electricity notes
GoConqr OriginalElectric circuits and current electricity notes
The notes on this page cover charge and current, potential difference, resistance and power. They also reach static electricity, capacitance, domestic circuits and calculations in electric circuits. Each resource is made by a GoConqr user, so you can choose the treatment that fits what you are studying.
Choosing a starting point
Current and Potential Difference is a useful place to begin with definitions and units. Follow it with Resistance to look at resistors and total resistance in series and parallel. For a closer look at the relationship between current and voltage, open Ohm's Law.
Study with notes
After reading a section, explain the key terms in your own words and check them against the note. If you want to test your understanding or practice recalling terms, switch to a quiz or flashcards on the unit page. Explore the notes and choose a topic to work through.
Frequently asked questions
Which note should I start with?
Start with Current and Potential Difference if you want definitions of current and potential difference and their units. For resistance in circuits, try Resistance, which includes total resistance in series and parallel. You can then look for a more specific topic in the list.
Are these notes free to use?
Yes. Every note listed here is free to open and study, and you do not need an account. A free account can also save your quiz scores and let you make your own quizzes, mind maps, flashcards and notes.
Which levels and courses do the notes suit?
The notes are mainly at secondary level and are useful for school students studying electricity and teachers looking for class material. Some resources refer to GCSE Physics. Check individual titles and notes to find material that matches the topic or course you are working on.
