ASVAB Practice Test

In a parallel circuit, if one component fails, what happens to the other components?

1. They all fail

2. They continue to operate

3. They operate intermittently

4. They receive more voltage

The correct answer is: They continue to operate

In a parallel circuit, the components are connected in such a way that each one has its own separate path for the flow of electricity. This means that the failure of one component will not affect the flow of electricity to the others. The other components will continue to operate as normal. This is why option B, "They continue to operate," is the correct answer. Option A, "They all fail," is incorrect because, as mentioned, the failure of one component does not affect the others in a parallel circuit. Option C, "They operate intermittently," is incorrect because the flow of electricity will not be affected by the failure of one component. Option D, "They receive more voltage," is incorrect because the voltage in a parallel circuit is divided between the components regardless of any failures.
