  A. base, emitter, and collector

  B. base, positive terminal, and negative terminal

  C. emitter, amplifier, and collector

  D. base and two gates

  Correct Answer: A

  The three terminals a transistor must have are the base, emitter, and collector.

• Question 43:

  A primary advantage of using a Li-Ion battery instead of a NiMH battery in your cell phone is __________.

  A. Li-Ion batteries are lighter

  B. Li-Ion batteries last longer

  C. Li-Ion batteries don't interfere with signal quality

  D. none of the above

  Correct Answer: A

  Lithium-Ion batteries are much lighter than Nickel Metal Hydride batteries.

• Question 44:

  Electromotive force is another way of saying __________.

  A. frequency

  B. watts

  C. cycles per second

  D. voltage

  Correct Answer: D

  Electromotive force is the pressure of the current, so the term is another way of saying voltage.

• Question 45:

  

  This symbol means __________.

  A. ohm

  B. ampere

  C. high voltage

  D. wattage

  Correct Answer: A

  The symbol stands for ohm.

• Question 46:

  What special type of diode is commonly used to regulate voltage?

  A. capacitor

  B. transistor

  C. Zener diode

  D. LED

  Correct Answer: C

  Zener diodes are available in a variety of voltages.

• Question 47:

  The heat effect of current is created __________.

  A. when the pressure of the current in the wire breaks up impurities in the wire, creating heat.

  B. when the current in the wire decays electrons, causing them to move more quickly, creating heat.

  C. when the current overcomes resistance in the wire, creating heat.

  D. The heat effect of current is only theoretical; it has never been proven to exist.

  Correct Answer: C

  Heat effect occurs when electrical current must overcome the resistance of the wire. Heat effect can be quite obvious or very subtle.

• Question 48:

  When working with electricity, you should assume that all electrical equipment is alive unless you know for certain otherwise.

  This prevents __________.

  A. damage to circuits

  B. personal injury

  C. unnecessary labor

  D. overheating the equipment

  Correct Answer: B

  The greatest concern when dealing with electricity is personal injury.

• Question 49:

  What's the primary advantage of a quad band cell phone over a dual-band cell phone?

  A. transmission strength

  B. coverage area

  C. reception strength

  D. smaller phone size

  Correct Answer: B

  There are four frequency bands used throughout the world. A quad-cell phone would be able to access any of these frequency bands.

• Question 50:

  What effect does a speaker wire's gauge have on speaker sound quality?

  A. higher gauge wires are thicker with better sound quality

  B. lower gauge wires are thicker with better sound quality

  C. lower gauge wires are thicker with lesser sound quality

  D. hire gauge wires are thicker with lesser sound quality

  Correct Answer: B

  Unless a specific gauge is specified by the speaker manufacturer, you should always choose lower gauges for better sound quality.
