SUMMARY
The standard VOM (volt-ohm-milliammeter) multimeter measures current with a full-scale range of 50 microamperes. This means that the maximum current it can accurately measure is 50 microamperes, which is indeed a microampere measurement. The VOM also measures other electrical parameters, such as voltage, by utilizing appropriate series and shunt resistors to extend its measurement capabilities beyond the full-scale current limit.
PREREQUISITES
- Understanding of basic electrical concepts, including current and voltage.
- Familiarity with multimeter functions and measurements.
- Knowledge of series and shunt resistors in electrical circuits.
- Basic principles of analog meter movements.
NEXT STEPS
- Research the operation of analog multimeters and their measurement ranges.
- Learn about series and shunt resistor configurations for current measurement.
- Explore the differences between VOM and digital multimeters.
- Study the principles of full-scale deflection in analog meters.
USEFUL FOR
Electronics students, hobbyists, and professionals who work with multimeters and need to understand current measurement techniques and the functionality of VOM devices.
