ELECTRICITY Flashcards
What is electricity?
Different forms of energy are used to generate energy, formed by movement of electrons.
Define static electricity?
Not moving
Define static electricity in detail?
Buildup of charges that dont move, electrons collect on the surface of an object, due to friction, electrons transfer from one subject to another.
Define current electricity?
Moving
Define electric current in detail?
It’s the flow of electrons. It needs energy, pathway and a component.
What are examples of current/dynamic energy?
Motion/kinetic, sound, solar, heat and light energies.
What are some examples of static energy?
Elastic, nuclear, chemical, gravitational and electromagnetic energies.
What is an insultor?
Materials that do not allow electrons to pass along it.
Examples of an insultor?
Wool and cardboard.
What is a conducter?
Materials that do allow electrons to pass along it.
Examples of a conducter?
Copper and aluminium.
What is the series circuit?
It’s when all components are connected in a single path for current to flow. It’s not common in homes and failure affects all components.
What is the parallel circuit?
It’s when components are connected in a parallel and total current flow is shared between all components. Its commonly used in homes and failure only affects a part of the circuit.
