• Question 16:

  Using a fuse rated higher than the required current rating of a circuit can __________.

  A. protect your circuit better
  B. cause the fuse to blow more often
  C. lower your power usage for that circuit
  D. result in serious damage to your circuit
  D. result in serious damage to your circuit

  Using a higher rated fuse is dangerous and can result in serious damage to your circuit.

• Question 17:

  Electromotive force is another word for ___________.

  A. ohms
  B. volts
  C. amps
  D. current
  B. volts

  ---

  Explanation

• Question 18:

  If a 120-volt current is protected by a 25-amp circuit breaker, what's the largest number of watts an appliance can safely use?

  A. 1,200 watts
  B. 1,800 watts
  C. 3,000 watts
  D. 3,600 watts
  C. 3,000 watts

  ---

  Explanation

  Determine the wattage that could cause the circuit breaker to trip with this formula: Watts = Amperes ?Volts or 25 ?120 = 3,000 watts.

• Question 19:

  Electromotive force is another way of saying __________.

  A. frequency
  B. watts
  C. cycles per second
  D. voltage
  D. voltage

  ---

  Explanation

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

• Question 20:
