🔍 Key Concepts

• Electromagnetic coil used as the sensing element in analog meters • The classic movement used in many DC analog meters (ammeter, voltmeter, ohmmeter) • Difference between a basic mechanical meter movement and a general "transducer"

💭 Think About

• Which of these choices is historically known as the standard coil-and-pointer movement used in most older DC panel meters? • Which options describe specific mechanical meter movements, and which seem to be more general devices or used for other types of measurements (like pressure or frequency)? • Think about which term you have most often seen paired with analog DC test instruments in electronics or marine engineering texts.

✅ Before You Answer

• Identify which option is a well-known coil-and-permanent-magnet movement used in DC meters. • Eliminate any option that is primarily associated with pressure gauges rather than electrical meters. • Eliminate any option that mainly measures frequency instead of direct current or voltage.
