Q: Is current or volts the same at all points in parallel circuit?
Answer:
Volts. Each branch reads applied volts
Q: Open components in parallel branch have how much current?
Answer:
0 A
Q: Current is (blank) with an open in parallel branch
Answer:
Lowered
Q: What happens to current with a short in parallel branch?
Answer:
Increases to MAX
Q: Opening what series-parallel component will cause amps to be 0?
Answer:

Series component. Volts dropped across open
Q: Current (increases/decreases) if a parallel component opens in series-parallel
Answer:
Decreases
Q: With open in parallel branch of s-p circuit: series volt drops(increase/decrease) and parallel
volt drop (increase/decrease)
Answer:
Decrease, increase
Q: Current increases or decreases with short in series component (s-p circuit)
Answer:
Increases
Q: What happens to REQ when there is a short in a parallel branch (s-p circuit)
Answer:
Goes to 0 ohms (parallel volt drops are 0 volts)
Q: What happens to circuit values when a load is addedto voltage divider?
Answer:
Resistance down, voltage down, current up
