SOLUTIONS

S1. Ans.(c)
Sol. The term artificial aging in instrument is associated with permanent magnet.
Over a long period of time, permanent magnets are gradually demagnetized by the impact of heat fluctuation. The degree of deterioration depends on the type and material of magnet and the magnetic characteristics.

S2. Ans.(d)
Sol. The Schering bridge use for measuring the low permeability of the dielectric material.
NOTE:
The Schering bridge use for measuring the capacitance of the capacitor, dissipation factor, properties of an insulator, capacitor bushing, insulating oil and other insulating materials. It is one of the most commonly used AC bridge.

S3. Ans.(b)
Sol. Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines, and 3D printers.

S4. Ans.(c)
Sol. Ts α R2
So, the starting torque of a wound rotor induction motor can be increased by adding external resistance to the rotor circuit.

UPPCL 2021, UPPCL JE ELECTRICAL QUIZ |_40.1

So, the starting torque of a slip ring rotor induction motor can be increased by adding external resistance to the rotor circuit.
While high starting torques are desirable, high rotor resistance results in a relatively high slip during normal running operation. The high resistance causes increased losses and reduced efficiency during normal operation.

S6. Ans.(d)
Sol. Stack pointer: 16-bit register
