Electricity and Magnetism Flashcards
What is static electricity?
mainly produced by friction. Like going down a slide
What is matter
anything that has mass and takes up space
what are the charge rules
- opposites attract
- like charges repeal
- law of conservation of charge; charge cannot be created or destroyed, only transferred; net electric charge is always constant
what is an electric field
the area surrounding charged particles/objects within a force can be exerted on other particles/objects
what is an electroscope
a tool used to detect the presence and magnitude of an electric charge
how do you transfer conduction
direct touch
how do you transfer through friction
through rubbing
how do you transfer induction
through distance
what is static discharge?
the sudden flow of electric charge between two charged objects, due to the build-up of static electricity. like lightning
how do you remove the charge
grounding
what is electric current
the net movement of electric charge in a single direction
how is electric current measured
amps
what is a voltage difference
the push(force) that causes the charge to move
what is resistance measured by
ohms
what is resistance affected by
material
size of wire
length of wire
temperature of wire
