repel 2 positive or 2 negative charges Charges repel when they are alike ( 2 positive or 2 negative charges ). attract 1 positive and one negative Charges attract when they are opposite ( 1 positive and one negative ).
Resistance voltage current Resistance is equal to the voltage divided by the current. RV R = V I
What are the 2 types of circuits? What is the primary difference between them?
Series Parallel 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.
Which circuit has greater resistance? Which has brighter bulbs? Which will not be affected if one bulb burns out?
The series circuit will have greater resistance. The parallel circuit will be brighter and unaffected by a bulb burning out.
series 120 volts 24 amps resistance 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.
Back to Menu Final Jeopardy RV R = V I R120V R = 120V 24A R5Ω R = 5Ω 1Ω Since there are 5 light bulbs, the resistance of 1 bulb is 1Ω.

Who first described the parts of the atom and what charges did he give them?
proton electronneutron Benjamin Franklin gave the parts a positive ( proton ), negative ( electron ), and neutral ( neutron ) charge.
What is a circuit breaker and why is it important?
A circuit breaker opens a circuit so current can no longer flow. This helps protect from fires and other electrical hazards.
Name the 4 possible factors that can change the resistance of a wire and how you can adjust them to increase it.
Back to Menu Final Jeopardy The resistance of a wire depends on… thicker resists more 1.Thickness ( thicker resists more ) longer resists more 2.Length ( longer resists more ) metal vs. plastic 3.Material ( metal vs. plastic ) hotter resists more 4.Temperature ( hotter resists more )
What is pictured below? Label the 2 types of parts. Find the voltage if there is a current of 12 amps and a resistance of 3 ohms. 1 222
