Elenco Basic Electronic Experiments - Manual (Page 70)

Electronics..................... The science of electricity and its applications.
Emitter............................ The output of an NPN bipolar junction transistor.
Encode........................... To put a message into a format which is easier to transmit.
Farad, (F)....................... The unit of measure for capacitance.
Feedback....................... To adjust the input to something based on what its output is doing.
Flip-Flop......................... A type of transistor configuration is which the output changes every time it receives an
input pulse.
Forward-Biased............ The state of a diode when current is flowing through it.
Frequency...................... The rate at which something repeats.
Friction........................... The rubbing of one object against another. It generates heat.
Gallium Arsenide.......... A chemical element that is used as a semiconductor.
Generator....................... A device which uses steam or water pressure to move a magnet near a wire, creating an
electric current in the wire.
Germanium.................... A chemical element that is used as a semiconductor.
Ground............................ A common term for the 0V or “–” side of a battery or generator.
Henry (H)........................ The unit of measure for Inductance.
Inductance..................... The ability of a wire to create an induced voltage when the current varies, due to magnetic
effects.
Inductor.......................... A component that opposes changes in electrical current.
Insulator......................... A material that has high electrical resistance.
Integrated Circuit......... A type of circuit in which transistors, diodes, resistors, and capacitors are all constructed
on a semiconductor base.
Kilo- (K).......................... A prefix used in the metric system. It means a thousand of something.
LED..................................Common abbreviation for light emitting diode.
Leads.............................. The wires sticking out of an electronic component, used to connect it to the circuit.
Light Emitting Diode.... A diode made from gallium arsenide that has a turn-on energy so high that light is
generated when current flows through it.
Magnetic Field.............. The region of magnetic attraction or repulsion around a magnet or an AC current. This is
usually associated with an inductor or transformer.
Magnetism..................... A force of attraction between certain metals. Electric currents also have magnetic
properties.
Meg- (M)......................... A prefix used in the metric system. It means a million of something.
Micro- (
μ)....................... A prefix used in the metric system. It means a millionth (0.000,001) of something.
Milli- (m)......................... A prefix used in the metric system. It means a thousandth (0.001) of something.
Momentum..................... The power of a moving object.
Morse Code................... A code used to send messages with long or short transmit bursts.
NAND Gate..................... A type of digital circuit which gives a HIGH output if some of its inputs are LOW.
NOR Gate....................... A type of digital circuit which gives a HIGH output if none of its inputs are HIGH.
NOT Gate........................ A type of digital circuit whose output is opposite its input.
NPN................................. Negative-Positive-Negative, a type of transistor construction.
Ohm’s Law..................... The relationship between voltage, current, and resistance.
Ohm, (
Ω)......................... The unit of measure for resistance.
OR Gate.......................... A type of digital circuit which gives a HIGH output if any of its inputs are HIGH.
Oscillator........................ A circuit that uses feedback to generate an AC output.
Parallel........................... When several electrical components are connected between the same points in the circuit.
Pico- (p)......................... A prefix used in the metric system. It means a millionth of a millionth (0.000,000,000,001) of
something.
Pitch................................ The musical term for frequency.
