1. A series circuit with a voltage drop of 120 volts has a 2 Ohms
current of 24 amperes and two resistors in series. The
first resistor has a resistance of 3 Ohms. What is the
resistance in the second resistor?
2. A transformer has a primary coil with 12 turns and a
secondary coil with 4 turns. What is the turn ratio of
this transformer?
3. A step-down transformer with a turn ratio of 3:1 has
a primary coil with 36 turns. How many turns does it
have in its secondary coil?
4. Three 2-Ohm resistors are wired together in a circuit. 3 Ohms
Two of the resistors are wired together in parallel.
Their combination is then wired in series to the third
resistor. What is the total resistance of the three resis-
tors wired in this configuration?
5. When installing three 3/0 THHW copper ungrounded
conductors in electrical metallic tubing (EMT), what is
the amperage for each conductor with the tempera-
ture rating of a conductor in column 75°C, operating
in an ambient temperature of 40°C?
6. What minimum two-gang (old work) plastic box is re-
quired with two 14/2 and two 12/2 nonmetallic cables
with two devices, including integral clamp assembly
inside the box?
7. A 2-Ohm resistor and a 3-Ohm resistor are wired to- The total resistance of the
gether in a circuit. Which of the following is a true circuit is 5 Ohms when the
statement?

2-Ohm and 3-Ohm resis-
tors are wired in series
8. A 2-Ohm resistor and a 5-Ohm resistor are wired in Since the resistors are in
parallel. If there is a voltage drop of 10 volts across parallel, the voltage drop
the 5-Ohm resistor, what is the voltage drop across the across each resistor is
2-Ohm resistor? the same. Therefore, the
voltage drop across the
2-Ohm resistor would also
be 10 volts.
9. An application requires the use of moisture- and
heat-resistant thermoplastic insulated conductors.
Which code describes this type of insulation?
10. If 1.5 amperes of electrical current is flowing through 2 ohms
a resistor that is connected to a 3-volt voltage source,
what is the resistance of the resistor?
11. What size breaker is used in a dwelling unit panel for 20-ampere breaker
a hot water heater rated at 4,500 watts, 240 volts?
12. An application is designed to use No. 14 AWG copper
TW wire installed in free air. What is the ampacity of
this conductor?
13. Four resistors, A, B, C, and D, are wired together in a
circuit. Resistors A and B are wired together in parallel.
Resistors C and D are also wired together in parallel.
These two parallel combinations are then wired to-
gether in series. If 2 amperes of electrical current flow
through resistor A, 6 amperes flow through resistor
