Series Circuit
100
Do opposite charges attract or repel?
Attract
100
Define Voltage
the amount of work required to move each unit of electric charge between two points.
200
Define Electric Insulator
a material that does not allow electrons to flow easily
200
What particle has a positive charge?
Protons
200
Parallel Circuit
200
Do like charges attract or repel?
Repel
200
Define Resistance
the opposition to the flow of electric charges.
300
Define Electric Charge
A property that leads to electromagnetic interactions
300
What is it called when particles have no charge?
Neutrons
300
What is the difference between a series circuit and a parallel circuit?
A series circuit only has a single path for charges. A parallel has more than one.

The following image shows two circular objects. Each object has an electric charge, as shown:
What will happen to these objects when they are placed near each other?
They will move away from each other and repel.
300
Higher Resistance =
Lower Resistance =
= Flows cannot move easily
= Flows can move more easily
400
Define Electric Current
the rate of flow of electric charges.
400
An object can become electrically charged if it gains or loses which particles?
Electrons ;)

Most strings of outdoor lights are wired in a series circuit. Which of the following is the best reason why a string of outdoor lights should be wired in a parallel circuit and not a series circuit?
If one light burns out. The rest will stay lit.

Are Electrons located inside the nucleus or outside the nucleus.
Outside
400
Which wire will have higher resistance? (A or B)
Wire B: Longer, skinnier wire = Higher resistance
500
A charged object (A) comes into contact with an uncharged object (B). In the process, object A loses electrons and object B gains electrons. What is true about object B....Think charges.
Object B gained electrons and now, has a negative charge.
500
What are Electrons attracted to?
Positive charges (Protons)

A student is building a simple circuit with a battery, light bulb, and copper wires. When she connects the wires to the battery terminals, the light bulb does not light up. What could explain the reason for this???
The circuit is open and not closed.
500
What will happen when a negative charge (electron) and a positive charge (Proton) meet?
The will attract each other
500
Does Voltage exist even if there is no electric current?
Yes
