First, I'm studying nature science at a Cegep. Later, I would like to be an electrical engineer. An electrical engineer's job is to design, plan and analyze circuits and systems that use electricity, signals, and energy. In short, any technological problem that requires an expertise that is closely related to electricity calls for an electrical engineer. In order to understand the vocabulary that I will use later, I have created a glossary of electrical terms. This glossary contains about 25 words. They are all accompanied by a definition, pronunciation, a translation, a picture and an example. This makes it easier to understand all these words.
Ampere
noun
The standard unit of measurement for the strength of an electric current.
Example: This circuitry consisted of a power supply unit providing a constant 1 AMPERE through the samples.
fr: Ampère
Amplitude
noun
Magnitude or size of a signal voltage or current.
Example: This describes a wave with AMPLITUDE a R : where (which is the optical path difference).
fr: Amplitude
Anode
noun
Positive electrode (opposite of cathode).
Example: Firstly a pH gradient is set up involving an ANODE (low pH) and a cathode (high pH), an electric field is then applied which causes the amphoteric components to migrate.
fr: Anode
Bandwidth
noun
A range of frequencies within a given band, in particular that used for transmitting a signal.
Example: Flat fading is based on multipath time delay spread, where the BANDWIDTH of the signal is less than the coherence BANDWIDTH of the channel or the delay spread is less than the symbol period.
fr: Bande passante
Cathode
noun
Output electrode of the current in the electrolysis (opposite to anode).
Example: If the light is shone onto the CATHODE of an evacuated photocell, some of the photoelectrons can pass from the CATHODE to the anode, and so a small current is created.
fr: Cathode
Current
noun
A flow of electricity that results from the ordered directional movement of electrically charged particles.
Example: Electric current is the flow of electrons through a complete circuit of conductors.
fr: Courant
Diode
noun
A two-terminal passive circuit element, with a preferred direction of current flow.
Example: Semiconductor DIODE detectors can improve the efficiency and resolution but have other drawbacks.
fr: Diode
Electret
noun
A permanently polarized dielectric material; its electric field is similar to the magnetic field of a permanent magnet.
Example: Gerhard M. Sessler created and patented the foil-electret microphone in 1962.
fr: Électret
Fuse
noun
A safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe level.
Example: Example of Data and Clock Crosstalk Reduction Linear 5 V fixed positive voltage regulator 21 500 mA FUSE.
fr: Fusible
Inductor
noun
A component in an electric or electronic circuit which possesses inductance.
Example: Then the system for the controller and INDUCTOR has to be first order.
fr: Inducteur
Insulated
adjective
Covered in nonconducting material to prevent the passage of electricity.
Example: This means the gap between any conductor and INSULATED frame need not be bigger than a few millimetres.
fr: Isolé
Lineman
noun
A specialist technician who installs outside plant wiring (overhead circuits, power transmission lines).
Example: The meaning of LINEMAN is one who sets up or repairs electric wire communication or power lines —called also linesman.
fr: Monteur de ligne
Microwave
noun
An electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.
Example: MICROWAVE heating is due to an electrical field exerting a force on charged particles and dipoles.
fr: Micro onde
Multimeter
noun
An instrument designed to measure electric current, voltage, and usually resistance, typically over several ranges of value.
Example: The random error in the reading of the stopping voltage was estimated through the accuracy of the MULTIMETER.
fr: Multimètre
Photonics
noun
The branch of technology concerned with the properties and transmission of photons, for example in fiber optics.
Example: NMS Programmes including Time and Frequency , PHOTONICS and measurement for Biotechnology.
fr: Photonique
Plasma
noun
An ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge.
Example: The presence of charged particles makes PLASMA electrically conductive.
fr: Plasma
Resistance
noun
Opposition to current flow and dissipation of energy in the form of heat. Symbolized "R" and measured in ohms.
Example: Electrical resistance, or Ohm's resistance, which is important in the transmission of electrical energy.
fr: La résistance
Shunt
noun
A small value resistor connected around a metering element to carry most of the current; only a small part passes through the meter.
Example: A SHUNT is a device that creates a low-resistance path for electric current.
fr: Dérivation
Superconductivity
noun
The loss of all electrical resistance at inconveniently low temperatures.
Example: Ganin demonstrated SUPERCONDUCTIVITY at temperatures of up to 38 K for Cs3C60.
fr: Supraconductivité
Switchgear
noun
Switching equipment used in the transmission of electricity.
The way in which constituent parts are interrelated or arranged.
"the topology of a computer network".
Example: RESULTS Table 1 illustrates the accuracy of each TOPOLOGY.
fr: Topologie
Transceiver
noun
A device that can both transmit and receive communications, in particular a combined radio transmitter and receiver.
Example: A CB TRANSCEIVER of 2.7 MHz is normally used to send floating codes.
fr: Émetteur-récepteur
Transducer
noun
A device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa.
Example: For many of the experiments an additional 'receiver' TRANSDUCER was connected to another channel of the oscilloscope, which picked up the pulse once it had travelled through the sample.
fr: Transducteur
Trigger
Verb
Pulse used to initiate a circuit action.
Example: PORTC pins have Schmitt TRIGGER input buffers.
fr: déclencher
Voltage
noun
The force of an electric current, measured in volts.
Example: The information exists as a range of different types of quantities, for instance force in a mechanical system or a VOLTAGE in an electronic system.
