Electricity quiz Flashcards
Using 1 wire, 1 battery, and 1 bulb, how can you make the bulb light up?
Both ends of THE WIRE must touch metal. One end of the wire must touch the battery on the + or on the negative terminal other end must touch the metal threads or the soldered tip (both metal) The metal part of the bulb that is NOT touching must touch the available terminal.
Using 2 wires, 1 battery, and 1 bulb, how can you make the bulb light up?
Both ends of BOTH WIRES must touch metal. One end of one wire must touch the + term. One end of one wire must touch the - term. The other end of one must touch the soldered tip The other end of the other must touch the metal threads.
Using 2 wires, 2 batteries, and 1 bulb, how can you make the bulb light up?
+ term of one battery touches - term of other One end of one wire must touch the available + term. One end of one wire must touch the - term. The other end of one must touch the soldered tip The other end of the other must touch the metal threads.
Batteries in series: definition, advantages, disadvantages
1 single path for flow of electricity brighter doesn’t last as long because if 1 battery dies, light goes out
Batteries in parallel: definition, advantages, disadvantages
multiple paths for flow of electricity dimmer lasts longer
bulbs in series: definition, advantages, disadvantages
1 single path for flow of electricity simpler to make doesn’t last as long and more dim
bulbs in parallel: definition, advantages, disadvantages
multiple paths for flow of electricity harder to make lasts longer and brighter
energy
the ability to do work
2 types of energy
potential (stored) and kinetic (motion)
matter
anything that takes up space
3 forms of matter
solid, liquid, gas
atom
smallest piece of matter that still has all its properties
subatomic particles and 3 kinds
microscopic parts of an atom. proton, neutron, electron
proton (location, charge, and ease of movement)
in nucleus (middle). positive. don’t move easily
neutron (location, charge, and ease of movement)
nucleus. neutral or no charge, don’t move easily
electron (location, charge, and ease of movement)
orbits nucleus, negative charge, move easily
electricity
form of energy caused by movement of electrons
4 things electricity can produce
light, heat, motion, and sound
current
flow of (negatively charged) electrons through a circuit
charge
the result of atoms with an unequal number of protons and electrons. More protons: positive charge. More electrons: negative charge.
force:
the way two or more objects interact.
3 types of force
attraction (pull) repulsion (push) friction (rub)
static electricity
negatively charged electrons that move off the surface of one object and build up on the surface of another. The electrons do not move through a circuit. They rest on the surface of that object until they are released. This release is called electrical discharge.
electrical discharge
The loss of static electricity as negatively charged electrons move off the surface of an object
current electricity
the continuous flow of negatively charged electrons through a closed circuit
circuit
a metal path that electrons flow through when it is completely closed. The flow of electrons stops when the metal path is open.
battery
a container holding materials that produce electricity
filament
the thin wire inside a bulb that gives off light and heat when electrons flow through it.
insulator
a non-metal object that stops the flow of electricity
conductor
a metal object that continues the flow of electricity
bulb
glass enclosed object that glows when electrons flow through it
wire
strip of metal that connects different parts of a circuit
volt
measurement of electrical force
series circuit
a type of circuit with only one path for the flow of electrons. brighter but does not last as long
parallel circuit
a type of circuit with multiple paths for the flow of electrons. lasts longer but not as bright.
how is static electricity like current electricity? How different?
Like: involves movement of electrons Different: electrons do not move through a circuit.
if a bulb does not light, what kinds of things would you check in your circuit and how would you check them?
