🔍 Key Concepts

• RF (Radio Frequency) currents and how they differ from DC or low-frequency AC • Operating principles of a hot wire ammeter • Operating principles of a thermocouple ammeter

💭 Think About

• Which types of meters can accurately respond to rapidly changing currents at radio frequencies? • Do traditional electromagnetic (moving-coil or moving-iron) meters work well at high RF, or do they have limitations? • How do heat-based measurement methods (like heating a wire or junction) relate to measuring RF currents?

✅ Before You Answer

• Verify which meter types measure current by heating effects rather than direct magnetic deflection • Check whether both listed meter types are specifically designed to work at high frequencies (RF range) • Confirm that any meter chosen can provide a true indication of RF current, not just DC or low-frequency AC
