Question

Driving torque is small and is adjustable.

(a) True

(b) False

This question was addressed to me in an interview for internship.

I need to ask this question from Friction and Overload Compensation topic in division Measurement of Power and Related Parameters of Electrical Measurements

Answer 1

The correct choice is (a) True

Explanation: Interaction between the parts of the shaded and unshaded fluxes, obtained through a shading loop leads to a small driving torque. The value of the torque can be adjusted through lateral movement of the loop.
