HAM Radio test questions & answers
2024/2025

Voltage - ANSWERSElectromotive Force, or EMF, force that causes electrons to flow in a circuit (E)



Volt - ANSWERSUnit of electromotive force



12 Volts - ANSWERSAmount of voltage that a mobile transceiver usually requires



Current - ANSWERSFlow of electrons in an electric circuit (I)



Amperes - ANSWERSMeasurement of electrical current



Direct Current - ANSWERSCurrent that flows only in 1 direction



Alternating Current - ANSWERSCurrent that reverses direction on a regular basis



Resistance - ANSWERSAmount of current suppressed (R)



Frequency - ANSWERSDescribes the number of times per second an alternating current reverses
direction, measured in Hertz



Copper - ANSWERSGood electrical conductors, used to connect a power supply to a radio



Glass - ANSWERSInsulator, has high resistance, which means it does not conduct electrical current very
well



Power - ANSWERSRate at which electrical energy is used

,Watts - ANSWERSMeasurement of power (W)



Ohm's Law - ANSWERSE = I x R

Voltage = Current x Resistance



Power Formula - ANSWERSP = E x I

Power = Voltage x Current

Micro - ANSWERS1-millionth of a quantity



Pico - ANSWERS1-billionth of a quantity



Kilo - ANSWERS1-thousand of a quantity



Mega - ANSWERS1-million of a quantity



Giga - ANSWERS1-billion of a quantity



3 dB Amount of Change - ANSWERSPower increase from 5 watts to 10 watts, 2:1, measured in decibels



-6 dB Amount of Change - ANSWERSPower decrease from 12 watts to 3 watts, 4:1, measured in decibels



10 dB Amount of Change - ANSWERSPower increase from 20 watts to 200 watts, 10:1, measured in
decibels



Resistor - ANSWERSOpposes flow of current in a DC circuit

,Potentiometer - ANSWERSVariable resistor whose resistance can be adjusted



Capacitor - ANSWERSStores energy in a electric field



Capacitance - ANSWERSAbility to store energy in an electric field, consists of two or more conductive
surfaces separated by an insulator



Farad - ANSWERSUnit of capacitance



Inductor - ANSWERSAbility to store energy in a magnetic field, typically composed of a coil of wire



Inductance - ANSWERSAbility to store energy in a magentic field



Henry - ANSWERSUnit of inductance



Switch - ANSWERSConnects or disconnects electrical circuits



Fuse - ANSWERSProtect other circuit components from current overloads



Carbon-Zinc - ANSWERSBattery type, non-rechargeable



Rechargeable - ANSWERSNickel-metal hydride, lithium-ion, lead-acid gel-cell



Diode - ANSWERSAllows current to flow in only one way



Anode and Cathode - ANSWERSThe two electrodes of a diode, cathode lead identified with a stripe



LED - ANSWERSLight-Emitting Diode, lights up when current flows through

, Transistors - ANSWERSUses voltage or current signal to control, amplifies signals, made of 3 layers of
semiconductor material



Gain - ANSWERSTransistor's ability to amplify a signal



Emitter, Base, Collector - ANSWERSThree electrodes of a PNP or NPN transistor



Field Effect Transistor - ANSWERSFET, has 3 leads like NPN and PNP transistors



Source, Gate, Drain - ANSWERSThree electrodes of a field effect transistor



Schematic Symbols - ANSWERSStandardized representations of components in an electrical wiring
diagram



Transformer - ANSWERSCommonly used to change 120V AC house current to a lower AC voltage for
other uses



Rectifier - ANSWERSChanges an alternating current into a varying direct current signal



Variable Inductor Component, Antenna Component - ANSWERS#3, #4



Simple resonant or tuned circuit - ANSWERSInductor and capacitor connected in series or parallel to
form a filter



Relay - ANSWERSSwitch controlled by a magnet



Meter - ANSWERSDisplays signal strength on a numeric scale
