Answer
A
If one bulb goes out, the other bulbs go out.
B
If one bulb goes out, the other bulbs stay lit.
C
If there is a break in one branch of the circuit, current can still flow through the other branches.
D
If there is a break in one branch of the circuit, current cannot flow at all.
E
Parallel circuits are simple to design and build.
F
Parallel circuits are complicated to design and build.
Explanation
In a parallel circuit, each bulb has its own branch, so if one bulb goes out, current can still flow through the other branches and those bulbs stay lit. A break in one branch therefore does not stop current throughout the whole circuit; the correct choices are “If one bulb goes out, the other bulbs stay lit” and “If there is a break in one branch of the circuit, current can still flow through the other branches.”
