Question
1) When A is unscrewed, what happens to the current through 3, 4, and 5? The current in ....
stays the same
increases by some amount
decreases to zero
decreases by some amount
2) Bulb A is screwed back in. What happens to the brightness of each of the three bulbs when bulb C is unscrewed and removed from its socket? Explain your reasoning.
C goes out but A and B stay the same because C is in parallel to A.
A stays the same, B and C go out. This is because B and C are in parallel to A and when C is removed it disconnects only B and C from the battery.
A stays the same because it is in parallel to B and C. C goes out because it is removed from the circuit. B gets brighter because current going through B is used to light only B which before unscrewing C was used to light both B and C.
All the bulbs go out because unscrewing and removing C makes the circuit incomplete.
3)When C is unscrewed, what happens to the current through points 3, 4, and 5? The current in
a.decreases to zero
b.stays the same
stays the same
b.increases by some amount
c.decreases to zero
d.decreases by some amount

Explanation / Answer
1 a.
2 A stays the same because it is parallel to both B and C . C goes out because it is removed from the circuit . B gets brighter because current going through B is used to light only B WHICH BEFORE UNSCREWING C was used to light both B and C.
3.b. STAYS THE SAME.
