What is zero error in ammeter?

Zero error in an ammeter occurs when the needle on the display does not point to zero when there is no current passing through it. This can happen due to manufacturing defects or calibration issues. Zero error needs to be accounted for and corrected to ensure accurate measurements.


When is an ammeter sensitive or accurate?

An ammeter is considered sensitive and accurate when it has a high degree of resolution and can detect small changes in current without significant error. Sensitivity is often enhanced by using a low internal resistance, which minimizes the impact on the circuit being measured. Accuracy is also influenced by calibration and the quality of the components used in the ammeter. Generally, digital ammeters tend to offer greater accuracy and sensitivity compared to analog ones.
