EES-101 Electrical Week 1 Pre-Test

1. Capacitors are categorized by all the following criteria, EXCEPT:

• Capacity

• Type of dielectric material

• Ability to prevent internal arcing

• The way they are constructed

2. Microprocessors may require all the additional things (that other integrated circuits do not), EXCEPT:

• Internal operating system

• External keyboard

• Serial data bus

• Different types of memory

3. What feature of a microcontroller distinguishes it from a microprocessor?

• External operating system

• Hardware located on the chip

• Sophisticated integrated circuit

• Programmed instructions

4. When discussing FET operation, Technician A says that when field effect creates conduction in the P or N channel, it is operating in depletion mode. Technician B says enhancement mode means that progressively increasing the voltage applied to the gate reduces or resists current flow through the source-drain channel. Who is correct?

• Technician A only

• Technician B only

• Both Technician A and Technician B

• Neither Technician A nor Technician B

5. What can easily damage FETs while being handled by a technician?

• Electrostatic discharge

• Current fluctuation

• Moisture

• High temperature

6. When the P material is connected to the positive terminal and the N material to the negative terminal, the diode is __________.

• Reverse biased

• Neutral

• Forward biased

• Positively charged

7. 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

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

• Multimeter

• Ohmmeter

• Graphing meter

• Ammeter

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

• Ammeter

• Voltmeter

• Auto-ranging meter

• Ohmmeter

10. 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
