ETEA MDCAT 2022 PAPER ETEA 2022 (PART 10) 1. When two conductors each of resistance R are attached in series to external circuit, their net resistance is: 3R 4R 2R R 2. An ideal AC generator has equal input and output, its heat dissipation will be: Very much small Maximum Zero Of some finite value 3. The unit of magnetic flux is NA-2 m-2 Tesla NA-1m1 NA-1m 4. AC generator stops suddenly when Moment of inertia of the coil decreases Resistance of the coil produces heat External voltage overcomes the back emf Torque of back emf exceeds the external torque 5. Output current of a half wave rectifier is: AC current Unidirectional current Straight line parallel to vertical axis Zero always 6. The resistance of full wave rectifier is Less than the resistance of half wave rectifier Negligible in comparison to the resistance of half wave rectifier Equal to the resistance of half wave rectifier More than the resistance of half wave rectifier 7. An electron will have maximum kinetic energy when it has: Low frequency Circular motion Short wavelength Long wavelength 8. When AC is converted to DC, the process is called Rectification Magnification Resolution Amplification 9. In pair annihilation two gamma ray photons created, travel in opposite direction not in the same direction, because This proves law of conservation of charge This proves law of conservation of energy This proves law of conservation of mass-energy This proves law of conservation of momentum 10. The radiation emitted by warm blooded animals lies in the region of: Ultraviolet Visible Infrared X-rays Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
