When measuring current on a meter, what relation should the meter capacity have to the expected amperage?

When measuring current with a meter, it is essential for the meter's capacity to be higher than the expected amperage. This ensures that the meter can handle the maximum current without risk of damage or incorrect readings. If the meter is not rated to accommodate the full expected current, it may lead to improper measurements, and in some cases, the meter could become damaged due to overloading.

Having a meter with a capacity that is higher allows for some margin of safety, accommodating any unexpected spikes in current while still providing accurate readings for normal operations. This principle is especially important in practical settings, such as electrical circuits, where variations in current can occur. By using a meter with a higher capacity than anticipated, users can confidently conduct their measurements without concerns regarding equipment failure or inaccurate data collection.
