Analog meters are devices that measure physical quantities, such as voltage, current, or resistance, using a needle and a dial. The needle moves along a scale to indicate the measurement, providing a visual representation of the value. These meters are often used in electrical and electronic applications for their simplicity and reliability. Unlike digital meters, which display readings in numbers, analog meters can show trends and fluctuations more easily due to the continuous movement of the needle. Common types of analog meters include voltmeters, ammeters, and ohmmeters, each designed for specific measurement tasks in various fields.
