C)series.
D)haste.

Question

Quizplus · Accepted Answer

When two electrical components are connected in series, they are connected one after the other, meaning that the current flows through one component and then through the other. If one of the components fails, the circuit is broken and no current can flow, which would explain why both headlights would fail when one bulb burned out. In contrast, when components are connected in parallel, each component has its own path for current to flow, so if one component fails, the other can still function independently. Choice D, "haste," is not a valid electrical connection type.
