IDA Quiz Week 9

Which of the following resistence readings can be interrupted as start to run?

• 4.3ohms

• 3.8ohms

• 2.5ohms

• 5.0ohms

A capcitor's rating is 35/5 (+/- 5%) The mircofarrads found at the fan are 4.1 and 30 at Herm. Is this capacitor good?

• Yes

• No

• Maybe

• I was looking at my phone.

The max current draw found at start up is called?

• Lock Fan Amps

• Inrush Current

• Commutation

• Voltage

Which of the following resistence reading indicate a run to common winding?

• 10ohms

• 50ohms

• .64ohms

• 14.7ohms

Where should a currnet draw be taken from?

• Start wire

• Run wire

• Capacitor herm

• Ground wire

What state should equipment be in before reading resistance or continuity?

• Off

• On

• During start up

• During normal operation

Why is it necessary to remove a component from a circuit before testing resistence?

• To prevent reading amperage across the start winding

• To ensure parasitic draw doesn't ruin multimeter battery life

• To ensure added resitence from the rest of the circuit isn't read

• It's not necessary.

If you perform a amp draw test and read 0 amps, this indicates...

• There is sufficiant continuity

• There is an open winding in the motor

• There is no current draw in that moment

• The contactor impedance is failing

For a 3 phase motor, what will the resistance be between common and start?

• lower than common to run

• higher that run to start

• lower than run to start

• equal to the rest

RLA is a reading of

• A motor's starting amperage

• A motor's resistence to heat

• A motor's RPM rating

• A motor's current draw during operation
