• Question 1:

  A galvanometer is usually used to measure ___________.

  A. volts
  B. current
  C. conductance
  D. resistance
  B. current

  ---

  Explanation

• Question 2:

  Another name for a transistor is __________.

  A. integrated circuit
  B. semiconductor
  C. transfer resistor
  D. rathbone connector
  C. transfer resistor

  ---

  Explanation

  The word "transistor" is a shortening of the term "transfer resistor". The transistor's original name when it was invented in 1933 was the "crystal amplifier".

• Question 3:

  A. 0.625 milliamperes
  B. 0.625 amperes
  C. 62. 5 milliamperes
  D. 625 amperes
  A. 0.625 milliamperes

  Explanation

• Question 4:

  Which of these is a symbol for a fuse?

  B

  ---

  Explanation

  The symbols shown are for the resistor, the fuse, and the capacitor, as well as for a lamp or light bulb. The one for the fuse is shown as in B.

• Question 5:

  How many diodes should you expect to find in a bridge rectifier?

  B. 4
  C. 8
  D. 10
  C. 8

  ---

  Explanation

  A bridge rectifier is also known as a full wave rectifier, usually containing 8 diodes.

• Question 6:

  Most 12 V car battery are made up of six individual cells connected in series. What is the voltage of each cell in a car battery?

  A. 2 V
  B. 3. 5 V
  C. 6 V
  D. 12 V
  A. 2 V

  ---

  Explanation

  Voltages in series are added to determine the total voltage, so divide 12 volts by 6 cells to get 2 volts. To be exact, each cell in a car battery provides 2. 1 volts for a total of 12. 6 volts when connected in a series and at full charge.
