Final answer:
The statement that v1 was selected as ground is false. In a circuit diagram, ground is a reference point used to measure voltage.
Step-by-step explanation:
Answer:
The statement that v1 was selected as ground is false.
In a circuit diagram, ground is a reference point used to measure voltage. It is typically represented by the symbol of a horizontal line with three vertical lines underneath it. By convention, the potential at ground is defined to be zero volts (0V).
Therefore, in a circuit diagram, the voltage at any other point in the circuit is measured relative to the ground. In other words, the voltage at v1 would be compared to the potential at ground.
So, in conclusion, v1 cannot be the ground as it would contradict the definition and purpose of ground in a circuit diagram.
