Charges repel when they are alike (2 positive or 2 negative charges).Charges attract when they are opposite (1 positive and one negative).What type of charge transfer does the picture show? Why does your hair get all frizzy?DAILY DOUBLE!

It shows Electric Fields, a force that surrounds the charged particle.

What are the 2 types of circuits? What is the primary difference between them?Who first described the parts of the atom and what charges did he give them?Describe what the picture below represents.

7What is Static Discharge? Give an example.How does a waterfall demonstrate Voltage?

Which circuit has greater resistance? Which has brighter bulbs? Which will not be affected if one bulb burns out?

What is a circuit breaker and why is it important?

Static Discharge is the loss of static electricity from an object. An example of this is lightning.

Describe how the last type of charge transfer works and give an example of when it is used.Why is it that birds sitting on power lines are not zapped? There are 2 reasons.You are building a series circuit with 5 light bulbs. If the power supply provides 120 volts and there is a current of 24 amps, what is the resistance of one bulb.Name the 4 possible factors that can change the resistance of a wire and how you can adjust them to increase it.

Potential Difference or Voltage.

Like water, current flows from areas of high potential to areas of low potential.High EPLow EP

Back to MenuFinal JeopardyThe birds have a higher resistance than the wire and they are not touching the ground or another wire.

Resistance is equal to the voltage divided by the current.

R = V I

The 2 types of circuits are Series and Parallel. The main difference is that Series has only 1 path for charge to take while Parallel has multiple.

The series circuit will have greater resistance.The parallel circuit will be brighter and unaffected by a bulb burning out.

Back to MenuFinal JeopardyR = V IR = 120V 24AR = 5Since there are 5 light bulbs, the resistance of 1 bulb is 1.

b) Electric fieldc) Voltagea) HeightElectric Potential depends on

Benjamin Franklin gave the parts a positive (proton), negative (electron), and neutral (neutron) charge.

A circuit breaker opens a circuit so current can no longer flow. This helps protect from fires and other electrical hazards.

Back to MenuFinal JeopardyThe resistance of a wire depends on

Thickness (thicker resists more)Length (longer resists more)Material (metal vs. plastic)Temperature (hotter resists more)
