Alternating current (ac)
| Глоссарий по экологии и "зеленой" энергетике |
- A type of electrical current, the direction of which is reversed at regular intervals or cycles. in the united states, the standard is 120 reversals or 60 cycles per second. electricity transmission networks use ac because voltage can be controlled with relative ease.
- Electrical current that continually reverses direction. the frequency at which it reverses is measured in cycles-per-second, or hertz (hz). the magnitude of the current itself is measured in amps (a). mains electricity is ac electricity.
- A type of electrical current, the direction of which is reversed at
- Alternating current is current that reverses its direction of flow at regular intervals. such current is frequently referred to as ac

Electrical, английский
Electricity, английский
- Электричество
- Energy resulting from the flow of charge particles, such as electrons or ions.
- The movement of electrons (a subatomic particle), produced by a voltage, through a conductor.
- Energy resulting from the flow of charged particles, such as electrons or ions.
- The fl ow of passing charge through a conductor, driven by a difference in voltage between the ends of the conductor. electrical power is generated by work from heat in a gas or steam turbine or from wind, oceans or falling water, or produced directly from sunlight using a photovoltaic device or chemically in a fuel cell. being a current, electricity cannot be stored and requires wires and cables for its transmission (see grid). because electric current fl ows immediately, the demand for electricity must be matched by production in real time.
Transmission, английский
- Passage of electromagnetic radiation through a medium.
- Transmisión
- The property in a merchantman, or a share therein, transmitted in
- Передача; привод; коробка передач; трансмиссия; прохождение; распространение ~ of loads передача нагрузок
- The transport of high voltage electricity. this is achieved with a transmission network (or grid). generally the network will connect large generators to lower voltage distribution networks where it will be transported to the majority of electricity consumers. alternatively, large scale electricity users may connect directly to the transmission network. management of transmission is a natural monopoly due to the economies of scale inherent to it. transmission system operator (tso) (also transmission network operator-
- The sending of information over a communications line or a circuit.
- The transportation of electric energy in bulk from a source or sources of supply to other systems or parts of a single system.
- Transfer of pathogens from one host to another
Controlled, английский
- Управляемый; регулируемый
- Управляемый
- Подконтрольный (о предприятиях)
Alternating, английский
- Current, synchronous на переменном токе, синхронный
- Current, volt напряжение переменного тока в вольтах
- Flemish bond a brickwork pattern which is produced by laying alternate
- Переменный; знакопеременный; альтернативный
- Знакопеременный (о силе, напряжении)`, чередующийся

Direct current (dc), английский
- A type of electricity transmission and distribution by which electricity flows in one direction through the conductor, usually relatively low voltage and high current. to be used for typical 120 volt or 220 volt household appliances, dc must be converted to alternating current, its opposite.
- Electrical current that flows in one direction only, although it may vary in magnitude. batteries produce dc electricity.
- A type of electricity transmission and distribution by which electricity
Amorphous silicon, английский
- A thin-film, silicon photovoltaic cell having no crystalline structure. manufactured by depositing layers of doped silicon on a substrate. see also single-crystal silicon an polycrystalline silicon.
- A non-crystalline form of silicon used to make photovoltaic panels.
- A thin‐film, silicon photovoltaic cell having no crystalline structure.
