HAM Technician Class UPDATED Exam
Questions and CORRECT Answers
Frequency - CORRECT ANSWER- describes the NUMBER OF TIMES per second that an
alternating current makes a complete cycle.
Symbol for Frequency - CORRECT ANSWER- f
Frequency - Unit of Measurement - CORRECT ANSWER- Hertz
Abbreviation for Hertz - CORRECT ANSWER- Hz
Wavelength - CORRECT ANSWER- is the name for the DISTANCE a radio wave travels
during one complete cycle.
Symbol for Wavelength - CORRECT ANSWER- λ
Wavelength - Unit of Measurement - CORRECT ANSWER- Meters
Abbreviation for Meters - CORRECT ANSWER- m
What is the formula for converting frequency to approximate wavelength in meters? -
CORRECT ANSWER- Wavelength in meters equals 300 divided by frequency in megahertz.
| λ in meters = 300 / f in MHz | [Wavelength in Meters = 300 / Frequency in MegaHertz]
Signals are considered WHAT above 20,000 Hz (20 kHz)? - CORRECT ANSWER- (RF)
Radio Frequency needs to be over THIS frequency?
Current - CORRECT ANSWER- is the name for the FLOW OF ELECTRONS in an electric
circuit.
Symbol for Current - CORRECT ANSWER- I | i
Current - Unit of Measurement - CORRECT ANSWER- Amps
Abbreviation for Amps - CORRECT ANSWER- A
Ammeter - CORRECT ANSWER- is used to measure CURRENT.
Voltage - CORRECT ANSWER- is the electrical term for the ELECTROMOTIVE FORCE
(EMF) that causes electron flow.
Symbol for Voltage - CORRECT ANSWER- E | e
Voltage - Unit of Measurement - CORRECT ANSWER- Volts
Abbreviation for Volts - CORRECT ANSWER- V
Voltmeter - CORRECT ANSWER- the instrument would you use to measure electric
potential or ELECTROMOTIVE FORCE.
Resistance - CORRECT ANSWER- is how much a material opposes the flow of electrons
through it.
Symbol for Resistance - CORRECT ANSWER- R
Resistance - Unit of Measurement - CORRECT ANSWER- Ohms
, Abbreviation for Ohms - CORRECT ANSWER- Ω
Ohmmeter - CORRECT ANSWER- used to measure resistance.
Power - CORRECT ANSWER- term that describes the rate at which electrical energy is used.
Symbol for Power - CORRECT ANSWER- P
Power - Unit of Measurement - CORRECT ANSWER- Watts
Abbreviation for Watts - CORRECT ANSWER- W
Ohm's Law Formula - CORRECT ANSWER- Voltage = Current x Resistance
Power Relationship Formula - CORRECT ANSWER- Power = Current x Voltage
Double of Wattage (Watts x 2) = an increase of how much dB? - CORRECT ANSWER- +
3dB
Increasing Wattage by a factor of 10 (Watts x 10) = an increase of how much in db? -
CORRECT ANSWER- + 10 db
Decreasing of Wattage by half (Watts / 2) = a decrease in how much dB? - CORRECT
ANSWER- - 3dB
Decreasing of Wattage by a factor of 10 (Watts / 110) = a decrease of how much dB? -
CORRECT ANSWER- - 10dB
Giga - CORRECT ANSWER- G | 10^9
Mega - CORRECT ANSWER- M | 10^6
