Ham Radio Technician License 2023-
2024 Exam-Graded A
Ham - ANS-Amateur Radio Operator
Elmer - ANS-Mentor
CQ - ANS-Come in any station, "general call"
QTH - ANS-What is your location?
CW - ANS-Morse Code
When should you use Morse Code - ANS-In the presence of interference or when
signals are weak
SSTV - ANS-Slow Scan Television
What precautions should be taken when using a multimeter? - ANS-Ensure leads are
rated for voltage, ensure set up and measurement goal are aligned
If you are measuring the resistance of a circuit and the reading starts low but gradually
increases, what does this indicate? - ANS-The presence of a large value, discharged
capacitor
Resistance (Definition, Symbol and Unit) - ANS-Opposition to flow of electrons, omega,
ohms
What measures resistance? - ANS-Ohmmeter
Electrons flow easily through ___________. - ANS-Conductors
Materials that resist electron flow are called: - ANS-Insulators
Olm's Law - ANS-V= I * R or V = E * R
Power (Definition, Symbol and Unit) - ANS-the rate at which energy is used, P, Watts
, In DC circuits, power is found by multiplying which two values? - ANS-Voltage (V) and
Current (I)
What is the function of a resistor? - ANS-To oppose the flow of electrons
What is the function of a capacitor? - ANS-To store electricity
Capacitance (Definition, Symbol and Unit) - ANS-Stored energy in a capacitor, F, farads
How do capacitors work? - ANS-They store electrical energy by creating a voltage
between two conducting surfaces (electrodes) seperated by an insulator called a
dielectric.
What is an inductor? - ANS-An inductor stores energy in the magnetic field created by
current flowing through a wire
Inductance (Definition, Symbol and Unit) - ANS-Energy stored in a magnetic field, H,
Henry's
How is an inductor made? - ANS-An inductor is made from a wire wound in a coil,
sometimes around a magnetic material to concentrate the energy.
What is a variable resistor called? - ANS-Potentiometer, or pot. Often used for volume
control.
What does a transformer do? - ANS-A transformer is a device that increases or
decreases voltage.
What is a circuit with both a capacitor and inductor called? - ANS-Resonant or tuned
circuit
What does a tuned circuit act like? - ANS-A filter, passing or rejecting signals at its
resonant frequency
Impendence (Definition, Symbol and Unit) - ANS-A combination of resistance and
reactance, X, ohms
T/F: Impendence is a general term to to mean a circuits opposition to the flow of
electrons - ANS-True
What is a diode? - ANS-A semiconductor that only allows current flow in one direction
What are heavy duty diodes are called? - ANS-Rectifiers
The result of AC current flowing through a diode it a... - ANS-Pulsing circuit
