chapter 10 Flashcards
Count Volta
Italian scientist, in 1800 he invented the voltaic pile, the predecessor to the modern battery. THis was the first time scientists had a reliable source of electricity.
Protons have a ____ charge
+ positive
electrons have a _____ charge
- Negative
Nuetrons have a ____ Charge
nuetral charge
Protons and Nuetrons are located where
In the middle of the atom
Electrons are located where
around the outside of the atom
Accumulated electrons
static electricity
Conduction
electric charges flowing through a medium, like metal wires
induction
when the electrons move around because of them being around eachothether. pushing the object in question
an electrical current always runs fom
the negative to the positive
how to properly draw a diagram of an electrical flow
look at notes, I drew it there
Pump (analogical battery)
makes the water flow by creating a difference in pressure. The water will always flow from high to low pressure
pipe ( analogical wire)
provides a contained pathway for the water to flow
water ( analogical electricity current)
flows in the pipes. flowing water actually consists of many individual molecules moving along In the pipe.
filter ( analogical resistor (like a lightbulb) )
procides resistance to the flow of water. the resistance depends on how tightly the filter is packed. it’s doing a practical job (cleaning the water) and that’s why we even have the water circuit.
