EES-101 Ch 13

Self-powered test lights are like regular test lights except that they contain a __________ battery.

• 0.3-volt

• 24-volt

• 12-volt

• 1.5-volt

If a test light illuminates between chassis ground and component ground, what does this most likely indicate?

• Parasitic draw

• Excessive amperag

• Missing ground connection

• Blown fuse

Which of the following symbols represents the electrical unit of measurement for sound?

• Ù

• dB

• nF

• Hz

Technician A says a multimeter measures resistance, continuity, voltage, and amperage. Technician B says the multimeter can be used to measure circuit resistance in amps to determine whether it is within specifications. Who is correct?

• Technician A only

• Technician B only

• Both Technician A and Technician B

• Neither Technician A nor Technician B

Which of the following uses a thermocouple accessory to measure temperature by contact?

• Multimeter

• Ohmmeter

• Graphing meter

• Ammeter

In powered circuits, which of the following are placed around a conductor and are used to measure amperage?

• Probing tips

• Inductive amp clamps

• Alligator clips

• Probingwires

Technician A says that before using a digital multimeter ,one of the first things to check is whether it is shunts or fuses are in place and functioning. Technician B says shunts do not operate like fuses and do not have a maximum rang. Who is correct?

• Technician A only

• Technician B only

• Both Technician A and Technician B

• Neither Technician A nor Technician B

What type of meter is not to be used with semiconductors and is potenally inaccurate when testing diodes?

• Ammeter

• Voltmeter

• Auto-ranging meter

• Ohmmeter

DC inductive amp clamps typically use__________.

• Hall effect technology

• Current transformers

• Separate magnetic fields

• Source voltage

Practices to observe when connecting an ammeter in series to measure amperage include:

• Connecting the meter in parallel to observe voltage drop

• Ensuring that the circuit is disabled

• Connecting the positive lead to the volts/ohms port and the negative lead to the common port

• Observing polarity when measuring DC voltage, but not AC voltage
