Electric Current & Circuits
What current is, how to draw a circuit, and the real difference between series and parallel.
What this lesson covers
Electric Current & Circuits is a 10-part Class 7 Science lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
An electric current is a flow of charge around a complete circuit. It is measured in amperes (A) with an ammeter. The circuit must be a complete loop: break it anywhere and the current stops everywhere in that loop.
