A level Current Electricity Quiz 2

16 Questions

Quiz Description

In this quiz, we will be focussing more on current electricity which as earlier seen we use daily for charging up electrical devices and use in circuits for light. Physics quizzes like this one often have technical problems and taking this quiz will help you understand more about current electricity. 

Current electricity is simply an electric charge in motion. Electric current which is measured in amperes is the number of charges that move through the wire per second. If we want current to flow directly from one point to another, we should always use a wire that has as little resistance as possible. Current electricity is used in almost all electrical devices used nowadays by man. For example, laptops with batteries have stored electrical energy. Electric current is connected throughout a house by applying an emf. 

To test your knowledge of electric current as well as related topics in physics, be sure to take our quizzes as this quiz will help you in your upcoming Exams. We have students preparing for tests, GCE exams, and GCSE exams taking most of these Quizzes as well, so be sure not to miss out, they are of course free.
Good luck!
