Electric Current and Potential Difference

Start with current and charge

Begin with the note Charge and Current. It describes electric current as the rate of flow of charge and introduces the idea of charged particles moving. The Electric current flashcard deck then asks for the definition of current, the unit of charge and the equation for current. Use the cards to practice recalling those points after reading the note.

For a visual overview, open the Charge and Current mind map. Its branches connect current, charge and the role of electrons in a metal wire. Compare those branches with the note, then return to the flashcards to check which terms you can explain without looking.

Add potential difference

The note Current and Potential Difference introduces current as the flow of electrical charge and potential difference as the driving force that pushes current around a circuit. It also gives the units for each. Read it alongside the Current and Voltage mind map, which describes current flow and what happens when a circuit is broken.

The Current and Voltage flashcards offer questions about current, voltage, their units and the equipment used to measure them. Work through the cards, then look back at the map when you want to review a connection.

Use a quiz to continue

The page also lists quizzes, including Current and Electric current. Try one after studying the notes and maps. Use its questions to guide another look at the resources, rather than treating a single score as the end of your study.

This topic is one section of Electric Circuits and Current Electricity in Physics. The page brings its notes, maps, cards and quizzes together, so you can move between explanations and practice within that unit. Choose a map and a quiz to work through together.
