A silicon diode, when compared to a germanium diode has less forward bias voltage the same forward bias voltage a higher forward bias voltage None 2. A resolver has 2 coils on the rotor and 3 coils on the stator 3 coils on the rotor and 2 coils on the stator 2 coils on the rotor and 2 coils on the stator None 3. In an integrated circuit, the components are inserted by doping in successive layers manually automatically None 4. TX is the abbreviation for a control transformer torque receiver torque transmitter None 5. The electrodes of an SCR are anode, cathode, source source, drain, gate gate, cathode, anode None 6. A transistor is used in both current amplifiers and voltage amplifiers voltage amplifiers current amplifiers None 7. In an ideal current amplifier input impedance must be low and output high input impedance must be high and output low both input and output impedances must be low None 8. A position gyro will provide acceleration feedback velocity feedback positional feedback None 9. An E&I bar output at datum has no induced voltage in the secondary windings an imbalance of voltages in the secondary windings equal and opposite voltages induced in the secondary None 10. An increase in amplitude of a rate feedback signal will cause unstable operation reduced hunting sluggish servo operation None 11. Using electron flow in a diode the current flows from Cathode to Base Cathode to Anode Anode to Cathode None 12. When compared to a photo diode, a photo transistor responds faster to changes of light is slower to respond to changes of light is less sensitive to light levels None 13. A thyristor is commonly used for voltage regulation rectification overvolts regulation None 14. In a Desynn indicator system, where is power supplied to Transmitter and indicator Transmitter only Indicator only None 15. Increasing velocity feedback from optimum will give sluggish performance faster performance no change on the output None 16. When a hole diffuses from the p region to the n region it becomes a minority carrier in the n region lowers the potential barrier raises the potential barrier None 17. A differential synchro can only be used as a receiver can only be used as a transmitter can be used as either a transmitter or a receiver None 18. Thermal runaway in a transistor refers to high current flow when temperature increases high current flow when temperature decreases low current flow when temperature increases None 19. The rotor of an autosyn position indicating system is an electromagnet spring controlled a permanent magnet None 20.
