DC Circuits and Circuit Analysis

What the page covers

The resources sit in the Electrical Principles and Circuit Theory strand of Electrical and electronic engineering. They start with the basics: circuit variables, circuit elements and simple resistive circuits. They then move on to analysis techniques, inductors and capacitors, and first-order RC and RL responses. The mind map on electric circuit analysis lays out that whole route in one view.

Where to start

If the vocabulary is new, begin with the flashcards. Electrical and Electronic Circuit Symbols and Resistor Color Codes help you read diagrams, while the Resistance deck covers resistor types. The notes on electric circuits fundamentals define a circuit as electrical elements connected in a closed path, then build up current and related quantities.

Moving into analysis

1. Work through the slide sets on calculating circuit resistance and on resistivity.
2. Use the flashcards on Ohm's law and on Kirchhoff's laws to fix the rules in mind.
3. Open the mind map on Thevenin and Norton, which explains how a source and impedance at a terminal port can replace a linear circuit.
4. Look at the maps on inductors and on differentiation and integration in circuit analysis for the more advanced ideas.

Using quizzes with maps

Read a mind map first, then test yourself. The quiz called Principles of basic electrical circuits asks about power in resistive circuits and about resistors in combination. CURRENT ELECTRICITY checks the basics of conductors and resistance. When an answer is wrong, go back to the matching map or deck and look at that branch again.

Who it suits

Most of the material is at university level, with a good share aimed at professional candidates and a smaller share for school students. Teachers can pick out maps, slide sets and quizzes to set as revision tasks.
