Moving Electricity
Question | Answer |
---|---|
What is Moving Electricity? | The flow of negative charges (electrons) |
The slow flow of electrons that allows energy to move quickly is called: | Electrical current |
Formula for current | Current= charge moving past a point/time |
Charge(Q) is measured in: | coulomb (C) |
Current(I) is measured in: | ampere (A) |
Time (t) is measured in: | second (S) |
Is the amount of current different or the same for each appliance? | different |
What is a conductor? | material that allows electrons to move |
What is a insulator? | any type of substance that resists or blocks the movement of electrons |
What does a circuit need to have in order to work? | a never-ending circle for the negative charge to flow through |
What are the 3 main components of a electrical circuit? | light bulb, battery and switch |
What is a ammeter? | A device used to measure the current in a circuit |
