Electric current in a/an ____________________ circuit travels in MORE THAN ONE path.
- A.
Series
- B.
Wire
- C.
Parallel
- D.
Connected
Correct Answer
C. ParallelExplanation
In a parallel circuit, electric current has multiple paths to flow through. This means that the current can divide and flow through different branches simultaneously. This is in contrast to a series circuit, where the current only has one path to follow. Therefore, in a parallel circuit, the electric current travels in more than one path.Rate this question:

In a ________________________ circuit, if one bulb burns out, the others will stay lit.
- A.
Parallel
- B.
Series
Correct Answer
A. ParallelExplanation
In a parallel circuit, the electrical components are connected in such a way that each component has its own separate path for the flow of current. This means that if one bulb burns out, the others will stay lit because they are still connected to the power source through their own individual paths. In contrast, in a series circuit, the components are connected in a single path, so if one bulb burns out, it breaks the circuit and all the other bulbs will also go out.Rate this question:

In a _________________________ circuit, if one bulb burns out, the others will not work.
- A.
Parallel
- B.
Series
Correct Answer
B. SeriesExplanation
In a series circuit, the components are connected in a single path, meaning that the current flows through each component sequentially. If one bulb burns out, it creates an open circuit, interrupting the flow of current. As a result, the other bulbs in the circuit will not receive any current and will not work.Rate this question:
