194 Multiple choice questions
Term 1 of 194
You would want to use a dual trace oscilloscope to measure:
the phase shift of a waveform
the total power output of a device
signal difference between two points
the frequency of a single signal
Term 2 of 194
In a 3 input AND gate:
3 input must be high for a high output
only one input must be high for a high output
2 inputs must be low for a low output
any input must be high for a low output
Term 3 of 194
Which motor maintains a constant speed with changing load?
Series
Shunt
Inverting
Compound
,Term 4 of 194
Some variable capacitors are made so the plates interleave. The capacitance varies as the plates
open(separate) and close. As they open:
Capacitance
The operating frequency
The capacitance decreases
Increase
Term 5 of 194
Applying positive voltage to the P end and negative to the N end of a germanium diode:
will forward bias it
90 degrees
half the original size
feedback and input resistors
Term 6 of 194
Which is least likely to cause ESD damage to MOSFET
slag
flux
current
voltage
,Term 7 of 194
The display of a DMM would probably be:
CRT
LCD
ROM
LED
Term 8 of 194
The energy stored in a coil is measured in:
Henrys
Joules
Farads
Ohms
Term 9 of 194
The output of a thermocouple would most likely be measured in:
milliamps
millivolts
125 volts
resistance
, Term 10 of 194
The power transformer in a power supply:
must be insulated from each other
A Z input for intensity modulation
maybe damaged by excessive speed
Might step voltages up or down
Term 11 of 194
You suspect the unit has an internal short. To prevent further damage when you apply power, you
should:
apply power directly to the unit
insert a low resistance high wattage(100ohm, 10w) resistor in series with the power input.
use a fuse to limit current flow
connect a high voltage capacitor in parallel
Term 12 of 194
A power source such as a generator or battery might be compared to what component in a water
supply system?
A valve
A low current digital display
A filter
A water tank
