When testing a capacitor with an analog or digital ohmmeter, the meter should:
a. Show no deflection or resistance and remain on an infinite reading.
b. Measure low resistance then return to high reading.
c. Display a zero measurement and stay there/
d. Measure a precise resistan@s and stay there.
Give this one a try later!
, b. Measure low resistance then return to high reading.
Relays are generally used to control inductive loads up to ___ amps.
а. 100.
b. 10.
C. 25.
d. 50.
Give this one a try later!
C. 25.
A diode is used to:
a. Control the direction of electron flow.
b. Increases inductive reactance.
C. Convert DC current to AC current.
d. Increase or decrease frequency.
Give this one a try later!
a. Control the direction of electron flow.
When testing the windings of a single phase motor:
a. The pair of terminals with the highest resistance will indicate that the other terminal
is the start.
, b. The common to start terminals show the lowest resistance.
C. The common to run terminals show the lowest resistance.
d. The start to run terminals show the lowest resistance.
Give this one a try later!
C. The common to run terminals show the lowest resistance.
When the temperature of a negative temperature coefficient (NTC) thermistor
increases, its resistance will:
a. Increase.
b. Decrease.
c. Remain the same.
d. Increase proportionately to the Delta T.
Give this one a try later!
b. Decrease.
Contactors are rated according to the maximum amperage through the:
a. Coil.
b. Contacts.
c. Thermostat.
d. Fuse.
