Why dont the electrical power lines trip when it rains if rain is a conductor of electricity?
Water is a very poor conductor of electricity and even if it has enough solutes in it to conduct electricity then it will still have a high resistance.
If rainwater were to conduct the electricity then that water would heat up and evaporate almost instantly.
But you need to remember that it would need a continuous channel of water to conduct electricity and the surface tension of water makes this unlikely to happen.
Additional AnswerOverhead conductors are supported using insulators, the shape of which is designed to (a) shed water, and (b) to provide a long conducting path for any moisture between the top of the insulator and the bottom. For high-voltage lines, several insulators may be used in the form of 'strings', providing a sufficiently-long conducting path for any moisture path to have a sufficiently high resistance to prevent conduction.
What else can I help you with?
How does electrical energy get to your home?
Through the national electrical grid that is composed of conductors to feed individual homes.
Why copper is used in electrical transmission line?
Copper is a good conductor and is fairly strong. It generally is not used in power transmission lines due to cost - generally aluminimum is used.
Who gets electricity from NS Power?
NS Power provides electrical power from as far north and east as Sydney to the southwestern city of Yarmouth. The high voltage lines from Sydney end at Dartmouth, and lower voltage lines extend further south and west towards Yarmouth.
Why are electrical circuits important?
Yes! Electricity is so imporatant. Think about it, if the power go's off in your house, it seems pretty dark. Electricity circulates in the power lines that go's underground and connects to different types of other cords to give us electricity! Well I hope that answer helped!
What system of high tension cables by which electrical power is distributed throughout region?
Power lines
How are electricity export or import?
Electricity is exported from the electrical power station that produces it and is imported into your home or business that uses it. This is done by way of electrical power lines and electrical sub stations.
What type of metal is a great conductor of electricity?
Silver is the best conductor of electricity, with copper a close second. Gold is third on the list followed by aluminium. Power distribution systems commonly use copper for underground power lines and aluminium for overhead lines.
What are electrical transmission towers for?
Electrical transmission towers are meant to hold the power lines and to carry electricity.
Can electricity flow through aluminium?
Yes, electricity can flow through aluminum. Aluminum is a good conductor of electricity, although it is not as efficient as copper. Aluminum is commonly used in power lines and electrical wiring because of its conductivity and cost-effectiveness.
What is an example of a conductor in a room?
The cord sending electrical power to a light bulb or a television is an example of a conductor of electricity in a room. A conductor of a choir or an orchestra is an example of a musical conductor in a room.
What are powerlines used for in electricity?
Power lines are used to transport or transmit electrical energy from the electrical generator to the customers. Power lines are important for they help factories, commercial buildings and residences have electrical energy.
A path for electricity to flow is a?
A path for electricity to flow is called a circuit. In a circuit, electrical current can flow from the power source through a conductor (such as a wire) to power an electrical device before returning to the power source. A complete circuit is necessary for electricity to flow.
Is rainwater an insulator?
Rainwater itself is not an insulator. In fact, water is actually a good conductor of electricity. When rainwater is present, it can increase the risk of electrical conductivity and may pose a higher risk of electrical accidents in certain situations, such as with outdoor electrical equipment or power lines.
When lines of force are cut by a conductor you have?
When lines of force are cut by a conductor, an electromotive force (EMF) is induced in the conductor according to Faraday's law of electromagnetic induction. This induced EMF can drive an electric current to flow in the conductor, resulting in the generation of electrical power.
Does aluminum conduct electricity?
Yes it does.Yes better than tin/aluminum foil. Im currently using it for my xbox360 controller.
What is a service lateral conductor?
service lateral conductors are the underground conductors between the utility electric supply system and the service point, basically the cables that bring power from the transformer to the power meter in an underground service
What are some ways a material's electrical resistance is used to accomplish a certain job?
A good example of electrical resistance is the heating element on a stove top it is a very poor conductor (high electrical resistance) because it is a poor conductor the electrical energy is converted to heat. Glass is one of the best insulators because its electrical resistance is so high it is a non conductor this lets us use it on high power lines to keep the electricity from coming in contact with the ground.
