Term Definition
What is an insulator? a material in which electrons cannot move easily from place to place
What is a conductor? materials that contain electrons that can move from place to place - move easily in the material
What is a series circuit? one that has only one path for the electric current to follow - if the path is broken, the current will no longer flow
What is a parallel circuit? one that has more than one path for the electric current to follow - if one path is broken, electrons continue to flow through the other paths
What is Ohm's Law? simple relationship among voltage, current, and resistance in a circuit - formula V = IR (voltage (in volts) = current (in ampheres) x resistance (in ohms)
What are some examples of insulators (know at least 3)? plastic, glass, wood, rubber, dry skin
What are some examples of conductors (know at least 3) ? copper, gold, silver, aluminum
What happens to an object when it loses electrons? it gains a negative (-) charge
What happens when an object gains electrons? it loses a positive (+) charge
What is included in a "SIMPLE COMPLETE CIRCUIT?" battery, wire, switch, and light bulbs
What causes a battery to work? a chemical reactions in the moist paste of the (+) and (-) terminals
What are two examples of a static discharge? lightning, static shock
What is voltage? the amount of energy a battery has - the measure of potential electric energy
Is dry skin a good conductor or a good insulator? an insulator
What does a negative terminal in a battery have? a pile up of negative charges
What is used in a parallel circuit to prevent it from overloading? fuses
What happened when we rubbed a balloon on our hair? Why was the paper attracted to the balloon? opposites attract - (balloon = (-) charge and the paper = (+) charge) it attracted the balloon because electrons have been collected
What is the filament in a light bulb made of? tungsten wire
Why is the filament in light bulbs made with tungsten wire? it does not melt easily, has a high resistance, can become hot enough to produce light
What direction do electrons flow in a battery? from the (-) terminal to the (+) terminal
What creates resistance in a wire? making it longer and thiner
What happend when two balloons were rubbed on our hair and then brought together? they repel each other
What is the difference between a series circuit and a paralle circuit? series has one path (one out = all out) while a parallel has more than one path
What is a watt and what does it measure? a measurement of a unit of power
What is volt and what does it measure? a measurement of electrical energy
What does an amphere measure? a measurement of current
What does an Ohm measure? a measurement of resistance
What happens when more volts are added to a flow of current? the current becomes stronger, increasing energy causes the lights to get brighter
What is the purpose of placing metal lightning rods at the top of tall buildings? for grounding - acts as a guide for lightning - so houses don't catch on fire
What is electric energy on the electric bill measured in? in kilowatt hours
What happens when you add devices (light bulbs) to a series circuit? light becomes duller because the current is decreased

Mexicanchickxxx : Oh my goodness. What did he say??
sillyshoez3 : lol nothing... he just said he read the note.
Mexicanchickxxx : oh that sux.... haha
sillyshoez3 : i no
sillyshoez3 : now its ackward between us
sillyshoez3 : like me and his parents
sillyshoez3 : im soon getting my ipod from him!
sillyshoez3 : but thats not the reason im going out w. him
sillyshoez3 : everybody thinks that though
sillyshoez3 : i love him sooo much

Mexicanchickxxx : Like hard to explain.
sillyshoez3 : did she get mad?
Mexicanchickxxx : No she didn't she just stared laughing at me.... Because I didn't know how to explain it...
sillyshoez3 : lol
sillyshoez3 : mhm. where's julie?
Mexicanchickxxx : No I'm serius. Sitting in her chair.
sillyshoez3 : lol
sillyshoez3 : duh
Mexicanchickxxx : hahaha she is retared!
sillyshoez3 : lol she can't find us
Mexicanchickxxx : Not really she is funny!
sillyshoez3 : she's still looking
Mexicanchickxxx : For this one??
sillyshoez3 : yeah
sillyshoez3 : or maybe she is still fighting w. those girls
sillyshoez3 : lol
Mexicanchickxxx : hahah what were they day??
Mexicanchickxxx : saying??***
sillyshoez3 : they were calling us bitches
