List Flashcards
Static electricity
It is created from friction(rubbing things together) eg clothes in a dryer,jumping on a trampoline
Current electricity
Flows of electrons ( negative particles)
Static discharge
Electron flow between two objects eg the spark you feel on a trampoline, the shock from a car door
Movement Of change
Electric current (eg i. A wire,a measured by a an ammeter
Magnets
Iron,combat or nickel metals the have been magnetized (all there electrons spin in the same direction)
Magnetic Field
Space around the magnet where magnetic force field can be felt
Magnetic field lines
Invisible lines that are draw. There indicates direction of the field (from N to S) the strength of the field (eg close together =strong
Atom
Smallest building block of all matter
Electron
Negative particle around of an atom; flows in wires in electrical circuit
Current
Flows of electrons (negative particles)
Electric circuit
Usually consists of a battery, switch bulls and resistors all connected so current can flow
Series circuit
one in which all circuit elements are arranged in a single path.
Parallel circuit
A parallel circuit has two or more paths for current to flow
Component
Uses energy in a circuit (eg lamp,resistor,speaker
Battery c
Supplies end to a circuit
