### Quiz Question

 1. Voltages are usually measured by placing the measuring device in parallel with the component or circuit (load) to be measured. The measuring device should have an infinite internal resistance input impedance) so that it will absorb no energy from the circuit under test and, therefore, measure the true voltage. True False 2. Figure 1-5 represents Ac-dc differential voltmeter, Digital multimeter 3. A major advantage of using an _____________ for ac voltage measurements is that the waveform can be observed; consequently, errors in measuring complex peak voltages are minimized. It may be used as a high-impedance ac voltmeter. Oscilloscopes Multimeters Voltmeters 4. In page 28, ______________ produce the large voltages that are required to measure resistances as high as 10,000megohms – only high resistance values can be measured. Meggers Bridges 5. The Hay Bridge (view B of fig. 1-14) differs from the Maxwell Bridge (view C) in figure 1-14. The difference is – for the Hay Bridge resistance associated with the capacitance is a series instead of a shunt resistance. True False 6. In pages 1-20 and 1-21 the Maxwell & Hay Bridges are used to calculate: Inductances Resistances 7. The factors affecting the life expectancy of the________ are listed in page 43. Electron Tube Klystron Tube 8. Electrostatic Discharge Sensitive (ESDS) devices can be grouped by their sensitivity to ESD as ____________ Very sensitive devices, Moderate sensitive devices, Sensitive devices All the above 9. RF diode test and switching diode test are the types of diode testers. True False 10. Figures 2-8 to 2-11 represent the different characteristics of different diodes. True False 11. Figure 2-23 represents: Types of ICs Types of diodes 12. The Wheatstone, Schering, Kelvin, Hay, Resistance-Ratio and Maxwell bridges are the basic bridge circuits as shown in page 3-2. True False 13. The resistance-ratio bridge, shown in figure 3-1, may be used to measure ___________________ so long as the electronic part to be measured is compared with a similar standard. Capacitance, inductance, or resistance Capacitance and inductance 14. The ________________ is used to measure power taken from ac or dc power sources. It uses the reaction between the magnetic fields of two current-carrying coils (or sets of coils), one fixed and the other movable as shown in figure 3-10. Electrodynamic wattmeter Converter 15. The absorption, the reaction, and the transmission types are three basic kinds of wave meters. True False 16. The Hewlett-Packard Model 415E SWR meter, shown in figure 4-3, is a commonly used SWR meter. True Flase 17. What does the formula for impedance represent on page 4-9? Impedance for a coaxial line Impedance of a Conductor 18. In page 4-11 the attenuation for a coaxial line is described in terms of decibels per foot. True Flase 19. Wave-Envelope and Trapezoidal Pattern are the two types of _____________ Modulation Patterns Waveform Patterns 20. Rate of frequency shift is inversely proportional to the frequency of the modulating signal. True False
