For a given load, the higher the supply voltage, the lower the resulting load current. So, using high voltages reduce the load current which, in turn:
- minimise voltage drop along the line (which, at low voltages, would otherwise be enormous, rendering transmission of energy impossible).
- enable conductors of practical size.
- reduce line losses.

How does electricity get to a plug?
The electricity is produced by large generators in a power plant.Transformers in the power plant yard step up the voltage to more than half a million volts used by the power transmission lines.Power transmission lines carry the electricity over long distances between the power plants and cities.Transformers in a switching yard step the voltage down to 1000 to 5000 volts used by power distribution lines.Power distribution lines carry the electricity short distances between the switching yard and the customer locations.Service drop transformers on the pole or underground step the voltage down to the voltage needed by the customer (e.g. 220 volts center taped for household, 240 volt 3 phase for commercial, 480 volt 3 phase for industrial).Service drop lines carry the electricity from the service drop transformer to the customer's electric meter.Internal main wiring carries the electricity from the electric meter to the breaker box.Wires from the breakers in the breaker box to outlets carry the electricity to the outlet sockets.When you put a plug in an outlet socket, the plug gets electricity.
What method of signal transmission uses radio waves to carry signals?
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
A steel tower supporting high-tension wires?
A steel tower supporting high-tension wires is a critical component of electrical transmission infrastructure, designed to carry high-voltage power over long distances. These towers are engineered to withstand environmental stresses, such as wind and ice, while maintaining structural integrity. Typically constructed from galvanized steel for durability, they ensure the safe and efficient transfer of electricity from power plants to substations and ultimately to consumers. Their design also minimizes the risk of electrical hazards and ensures compliance with safety regulations.
What materials are required to make hydro electricity?
To generate hydroelectricity, you would need the following materials: a water source such as a river or dam, a turbine connected to a generator, transmission lines to carry the electricity, and a control system to manage the flow of water and electricity production. The water flow turns the turbine, which then spins the generator to produce electricity. The transmission lines carry the electricity to homes and businesses. The control system ensures efficient and safe operation of the hydroelectric power plant.
What other equipment is involved in getting electricity to were it can be used bt people?
In addition to power plants, various equipment is essential for delivering electricity to consumers. Transmission lines carry high-voltage electricity over long distances, while substations step down the voltage for local distribution. Distribution lines then deliver the electricity to homes and businesses. Transformers also play a critical role in adjusting voltage levels throughout the process to ensure safe and efficient delivery.
Why are high tension electricity wires called that?
High tension electricity wires are called that because they carry electricity at very high voltages, typically ranging from 69,000 to 765,000 volts. These high voltages allow the electricity to be transmitted over long distances with minimal power loss.
Electricity travels through tansmission lines.metal towers are called...?
Metal towers that carry electricity transmission lines are called transmission towers or power line towers. These towers support the electrical conductors that transmit electricity over long distances.
What are electrical transmission towers for?
Electrical transmission towers are meant to hold the power lines and to carry electricity.
What is the word which means 'conductor carrying electricity over large distance with minimum losses' - clue it wl have a 'miss' syllable in it?
Transmission lines are used to carry electricity.
Information or data is transmitted in digital computers by voltages that are switched on or off?
voltages must be on before data information can be transmitted in digital computers and not so when using the internet, because the message is transmitted at the slightest glimpse of power source. does not need proper voltage to carry out transmission
Can you get an electric shock through the air?
yes, it's called lightning also in the case of high voltages the general rule of clearance is 1 foot for every 1000 volts. so those high tension towers you see can carry in excess of 13200 volts so if you get any closer than 14 feet the electricity could jump to you.
What do you call a material that can carry electricity?
An electrical conductor is a material that can carry electricity.
What materials will not carry or conduct electricity?
Insulator materials will not carry or conduct electricity.
What is a sentence with tension?
Relax, you carry so much tension in your shoulders.
How many transmission towers in the US?
There are approximately 220,000 transmission towers in the United States that are used to carry electricity across long distances from power plants to substations and eventually to homes and businesses.
How much voltage is used by electrical device?
minimum 230volts In formal electrical jargon, a "device" does not "use" electricity. A device is something like a switch or receptacle(outlet) that helps control or carry electricity but does not consume electricity. In the United States, voltage for home lighting and general purpose receptacles is 120v. Voltage for electrical appliances such as ranges, clothes dryers, or furnaces is 240v. Voltages such as 110v, 115v, or 125v are versions of 120v in electrical jargon and voltages such as 220v or 230v are versions of 240v.
How much electricity does a pylon Carrie?
In the UK a line of pylons carrying the supergrid at 400 kilovolts can carry up to about 2000 Megawatts. Pylons also carry circuits working at lower voltages, 275 and 132 kV, 66 kV in some places, and on small pylons 33 kV.
