16$300 Question from H2 Application: A battery switch and bulb are connectedby wires. Explain when the circuit would becomplete and when it would be incomplete?
17$300 Answer from H2 When the switch is down and letting electricity through it would be complete,but when it is up and not lettingelectricity through the circuit would beincomplete.
18$400 Question from H2 Synthesis: Can you elaborate on the reason why ifelectricity flows from minus to plus.Why would it not flow from the minusterminal if the positiveterminal wire is not connected.
19$400 Answer from H2 Without the positive terminal the electrons have no where to go to so they don’t move.orThe circuit is not complete without thepositive terminal.

23$100 Answer from H3Series Circuits can have only one path.
24$200 Question from H3 Comprehension: Daily Double In a series circuit of four lights whathappens to the third and fourth lightif the second one goes out?For Double points what happens to thefirst light.
25$200 Answer from H3 In a series circuit the third and fourth lights go out when the second one does.So does the first since all have to beworking in a series circuit.
26$300 Question from H3 Analysis: (Easy) When more bulbs are added to a series circuit explain why each wouldgive off less light.
27$300 Answer from H3 They are all part of the same load in a series circuit and use the samepath of electrons to light them all.
