Electric Circuits

Start with electrical principles

A useful starting point is the mind map on principles of electrical science. It introduces electron theory and describes the charges of protons and electrons. It also covers electrically neutral atoms. Use it to organize these ideas before moving to questions about particles and electrical flow.

The flashcards titled Science offer another starting point. They ask about open and closed circuits, current, how its strength is measured, and direct current. Read each question, form an answer, then check it against the card.

Move from maps to quizzes

After studying the principles mind map, try the quiz on fundamentals of electricity and circuits. It asks about negatively charged, positively charged and neutral particles in an atom. Return to the map when you need to check the ideas behind a question.

For another view of electrical flow, try Oil Electrical. Its questions include electron theory and conventional theory. You can also use the Science flashcards alongside it to study the language used to describe current.

Practice circuit concepts

The basic electricity quizzes include questions about power in a resistive circuit and resistance in parallel circuits. The flashcards on electrical fundamentals ask about current, potential difference, power loss, voltage drop and overheating. Use the cards to study the terms, then test your understanding with the quiz questions.

The mind map HND Electrical and Electronic Principles includes circuit theory. It offers another way to organize your study as you move between the flashcards and quizzes.

Use this section of the unit

Electric Circuits is a section of the unit in Electrical and electronic engineering. The resources bring together principles, circuit terminology and questions within that section. Choose the format that suits your starting point, then use another format to return to the same ideas. Pick a resource and begin exploring.
