Question

1. understanding the polarity of a power source such as a battery is critical when using a ground reference as only the negative terminal should be connected to the ground reference point.

true

false

Explanation:

Analyze the ground reference concept

Using the Ground Reference and Circuit Polarity knowledge points

• A ground reference is an arbitrary reference point in a circuit defined as \(0\text{ V}\).
• Either the negative terminal or the positive terminal of a power source can be connected to the ground reference.
• Connecting the positive terminal to ground creates a positive ground system, which is common in some telecommunication systems and older vehicles.
• Therefore, it is false that only the negative terminal should be connected to the ground reference point.

Answer:

• True
• False (Correct answer)
