🔍 Key Concepts

• Difference between RMS (root mean square), peak, and average values of AC current • What a typical analog or digital AC ammeter is calibrated to show • Relationship between AC heating effect and equivalent DC current value

💭 Think About

• When we say an AC ammeter reads the same as a DC ammeter for the same heating effect in a resistor, which quantity of the AC waveform is being measured? • Does common shipboard electrical equipment care more about the instantaneous peak of the current, or about the equivalent power/heat delivered over time? • Which of the listed quantities (TRM, RMS, peak, average) is standard for specifying AC supply values like 120 V or 230 V?

✅ Before You Answer

• Be clear on the definition of RMS value versus peak value for a sine wave • Confirm what quantity a standard commercial AC ammeter (without any special markings) is calibrated to indicate • Note whether TRM is a standard electrical measurement term compared to RMS
