Final answer:
False. In a circuit diagram, we cannot assume that the voltage is the same at every point in a given wire.
Step-by-step explanation:
False. In a circuit diagram, we cannot assume that the voltage is the same at every point in a given wire. Voltage is the electric potential difference between two points in a circuit, and it can vary depending on the components in the circuit and their arrangement. The voltage drop across a component is determined by its resistance and the current flowing through it. So, in a circuit diagram, the voltage may change across different points in a given wire.
