If an ammeter displays a positive reading, what does this indicate about the current flow?

• A. The current flows into the positive terminal
• B. The current flows out of the negative terminal
• C. There is no information obtained
• D. Current is modulated

Answer: (A)

When an ammeter displays a positive reading, it signifies that the current is flowing into the positive terminal of the meter. This behavior is inherent to the design of an ammeter, which is intended to measure current in a direct path through the circuit. In standard measurements, the current direction is defined conventionally such that current flow is considered to move from the positive terminal to the negative terminal in a circuit. Therefore, a positive reading demonstrates that the current is indeed entering the ammeter through its positive terminal, indicating the expected flow in the direction of conventional current. This understanding aligns with fundamental electrical principles, where the flow direction directly reflects how the circuit components interact with one another, allowing for accurate analysis and system operation assessments. Such measurements are essential for troubleshooting and ensuring the functionality of electrical circuits.
