Hi,my name is Binal taheem. I live in Saint-Eustache. I have been studying electrical engineering for 2 session at Ahuntsic college. My field of study is automation and control in electrical engineering. The glossary that I have made could be useful for student studying in electrical engineering and also for new students in this field. Each word in this glossary is related to the basic notion of electrical engineering. They are the most use word in this field. I chose these word because they where hard to understand when I started studying in electrical engineering.
alternating Current
noun
Alternating Current (AC) is an electrical current in which the flow of electrons periodically reverses direction, changing both magnitude and polarity at regular intervals, often following a sine wave.
Example: Household electricity is supplied as alternating current (AC).
fr: courant alternatif
capacitance
noun
Capacitance is the ability of an object, usually a capacitor, to store an electric charge and, by extension, electrical energy in an electric field. It is measured in farads (F).
Example: The capacitor has a capacitance of 10 microfarads.
fr: capacité
circuit
noun
An electric circuit is a continuous, closed loop or path formed by conductors and electrical components where electric current can flow.
Example: The light turns on when the circuit is closed.
fr: circuit
conductor
noun
An electrical conductor is a material that permits the easy flow of electric charge, or current, through it, due to the presence of loosely bound, free-moving electrons.
Example: Copper is a good conductor of electricity.
fr: conducteur
current
noun
Current is the rate of flow of electric charge. It is measured in amperes (A).
Example: The current flowing through the wire is 2 amperes.
fr: courant
diode
noun
A diode is a two-terminal electronic component that acts as a one-way switch for electric current, allowing it to flow in one direction (forward-biased) while restricting it in the opposite direction (reverse-biased).
Example: The diode protects the circuit from reverse current.
fr: diode
direct Current
noun
Direct current (DC) is an electric current characterized by the flow of electric charge in one single, unchanging direction.
Example: Batteries supply power in the form of direct current (DC).
fr: courant continu
inductance
noun
It is caused by the magnetic field generated around the conductor when current passes through it. When the current changes, this magnetic field induces a voltage (known as electromotive force or EMF) that opposes the change, as described by Lenz's Law. The unit of inductance is the henry (H).
Example: The inductor’s inductance reduces sudden changes in current.
fr: inductance
insulator
noun
An electrical insulator is a material that resists or prevents the flow of electric current.
Example: Rubber acts as an insulator around electrical wires.
fr: isolant
oscilloscope
noun
An oscilloscope is an electronic test instrument that visually displays an electrical signal, usually a varying voltage, as a waveform on a screen, showing how the signal changes over time.
Example: We used an oscilloscope to display the voltage signal.
fr: oscilloscope
power
noun
Power is the rate at which electrical energy is supplied or consumed by a circuit or device, measured in watts (W), where 1 watt equals 1 joule per second.
Example: The motor consumes 500 watts of power.
fr: puissance
resistance
noun
Electrical resistance is the opposition to the flow of electric current within a circuit or material, acting like friction for moving electrons. Measured in ohms (Ω).
Example: The resistor adds resistance to limit the current in the circuit.
fr: résistance
transformer
noun
A transformer is an electrical device that changes voltage and current in an AC circuit, working through electromagnetic induction to transfer electrical energy between circuits without a physical connection.
Example: The transformer reduces high voltage to a safer level.
fr: transformateur
transistor
noun
A transistor is a fundamental semiconductor device that functions as an electronic switch or amplifier, controlling the flow of electrical signals and power.
Example: The transistor amplifies the weak input signal.
fr: transistor
voltage
noun
The difference in electric potential energy between two points in a circuit, acting as an "electrical pressure" that pushes charged electrons, or current, to flow. It is measured in volts (V).
Example: One example of an hypothesis which has been given serious attention in recent years is the possible link between electromagnetic fields generated by high - VOLTAGE power lines or supply cables and ill health.
