Q

The D'Arsonval type meter consists of:

🔍 Key Concepts

• D'Arsonval meter movement basic construction • Role of permanent magnet, movable coil, jewel bearings, and spiral springs in analog meters • Difference between what supports the coil and what provides the restoring (controlling) torque

💭 Think About

• Think about which parts are absolutely essential for the D'Arsonval movement to operate and return to zero when current is removed • Ask yourself: what component actually produces the restoring force that brings the pointer back, and is that mentioned in each option? • Compare the wording of A and B: do they describe different parts of the same standard movement, or mutually exclusive designs?

✅ Before You Answer

• Verify whether spiral springs are a standard, necessary part of a D'Arsonval movement for providing restoring torque and electrical connection • Check if a permanent magnet is always used in the D'Arsonval type meter for the magnetic field • Confirm that jewel bearings are used to support the movable coil and allow low-friction rotation
