EXAMINATION TEST 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
⩥ A measure of the amount of energy stored by a capacitor. Answer:
Capacitance
⩥ Current measuring device that is not connected directly to the circuit
but instead temporarily clamps around the electrical wire. Answer:
Clamp-on Ammeter
⩥ The base unit of measurement for capacitance. Since a farad is a very
large unit, a much smaller unit is usually used. (See Microfarad)
Answer: Farad
⩥ A meter that can read millions of ohms of resistance. Answer:
Megohmmeter
⩥ The unit of measurement for capacitance, equal to a millionth of a
farad. Answer: Microfarads
⩥ A meter that reads multiple electrical properties, typically including
volts and ohms. Answer: Multimeter
,⩥ An meter for measuring electrical resistance. Answer: Ohmmeter
⩥ The rate of actual power as measured by a wattmeter in an alternating
circuit to the apparent power determined by multiplying amperes by
volts. Answer: Power Factor
⩥ Pressure or temperature settings of a control. Answer: Range
⩥ The opposition to current flow by a physical conductor. Answer:
Resistances
⩥ A material that conducts electricity better than an insulator but not as
well as a conductor. Answer: Semiconductors
⩥ Another name for ladder or line diagram. Answer: Schematic Wiring
Diagrams
⩥ The shape created when the voltage of an alternating current is
graphed. It appears like a regular set of repeating peaks and valleys
connected by a single smooth curve. Answer: Sine Wave
⩥ Uses frequent value sampling and the root mean square formula to
determine alternating current values. Answer: True RMS Meters
, ⩥ Independent standards and testing laboratory for the examination and
testing of devices. Answer: Underwriters Laboratories (UL)
⩥ A machine that converts mechanical energy into alternating current.
Answer: Alternator
⩥ Current that reverses polarity or direction with regular frequency. It
can be single phase, two phase, three phase, or polyphase. Answer:
Alternating Current
⩥ A furnace that generates either hot water or steam. Answer: Boilers
⩥ Type of electrical storage device used in starting and/or running
circuits on many electric motors. Answer: Capacitor
⩥ A device that senses current flow and opens when its rated current
flow is exceeded. Answer: Circuit Breakers
⩥ A wound conductor that creates a strong magnetic field when current
passes through it. Answer: Coil
⩥ Material or substance that readily passes electricity. Answer:
Conductor
