Final answer:
No. 14 AWG wire is indeed thicker than No. 16 AWG wire, which is true. In electrical diagrams, the voltage is not the same at every point in a given wire, which is also true.
Step-by-step explanation:
The statement that No. 14 AWG electrical wire is thicker than No. 16 electrical wire is true. In the American Wire Gauge (AWG) system, which is used to standardize wire sizes, a lower gauge number indicates a thicker wire. Therefore, a 14-gauge wire would have a larger diameter than a 16-gauge wire, allowing it to carry more current due to having a larger current-carrying capacity.
It is also important to understand that in a circuit diagram, we cannot assume that the voltage is the same at every point in a given wire. In fact, the voltage can change across components or over distances due to potential differences created by electrical devices or resistance. Thus, the appropriate answer to whether the voltage is the same at every point in a given wire on a circuit diagram is false.
