What is semi conductor diode?
Semiconductor diodes are made from the same Silicon, and occasionally Germanium, material that transistors, integrated circuits, etc. are made from. Diodes used in early electronic devices were made from vacuum tubes. Somewhat later diodes were made from finned stacks of Selenium. Simple "Crystal Radios" use Galena (lead ore) crystals with a steel pin that is manipulated to find a spot that allows electrical current to flow in only one direction.
Can I get example of Insulated overhead power lines more than 50kV with Images?
Voltages in that range do not use insulation around the conductor. They are bare conductors and use air and separation from one another for the insulation factor.
What reduces thetrnsfer of heat?
Insulation, use of a poor conductor of heat, dirt are some examples. You would need to be more specific if you have a particular question.
Does using transformers to create high voltages reduce wasted energy in power lines?
Yes. The two main reasons are:For a given size of power line more power can be carried by the line at higher voltage and lower amperage with less resistive heating. The heating due to resistance is a waste of energy. This due to Power = Volts X Amps. The higher the Volts the lower the Amps for some amount of Power. The more Amps carried by a conductor the more heat it will produce due to resistance.Since we can use a smaller size of power line to carry a given amount of power we will use less copper or aluminum to make that power line. The less material we use to make the conductor the less energy we have to use to make that conductor. Also the less energy it takes to transport, install, and support that conductor.
Why link is provided as neutral in an ac circuit?
link is provided in neutral path of ac supply because it should provide a path for unbalanced currents , if we use fuse ,fuse may blow of and damage the entire system and also unbalanced currents may be more than the fuse rating
What is ge germanium used for?
An Important Use Of Germanium Is That It's A Semi-Conductor (Semiconductor.) A Semi-Conductor Will Only Conduct Things, Such As Heat, So Well, And Only So Many Of Times You Try.
How do you use conductor in an sentence?
My uncle is a conductor for the rail system. Gold is a better conductor than silver.
Why is copper more widely used as an electrical conductor than silver?
Copper is more widely used as an electrical conductor than silver because copper is less expensive and has slightly lower electrical conductivity, but still high enough for most applications. Silver is a better conductor of electricity than copper, but its high cost makes it less practical for general use in wiring and electrical components.

Why use tungsten as an electrode?
Advantages are that Tungsten is a very good electricl conductor. Better than copper
Do you use a colon or semi colon to write a formal letter?
i would use a semi colon ; just because that is More formal.
Tessellation that use more than one type of regular polygon are called semi-regular tessellations?
A tessellation that uses more than one type of regular polygon in an isogonal arrangement is known as a emu-regular tessellation. There are eight semi-regular tessellations that can be described by their vertex configuration.Ê
Is silver wire a better conductor?
The best conductor of electricity is copper wire. Silver is a better conductor than copper, look up basic data. But silver is not practicable for widespread use, copper is nearly as good and more practicable for engineering use as well as cost.
Are uniform tessellation semi-regular?
Sometimes. By definition, a semi-regular tessellation must include more than one type of regular polygon. Some uniform tessellations use more than one type of regular polygon, but many uniform tessellations use only a single regular polygon. Therefore the statement is only sometimes true.
What is the difference between a semi flush and a full flush?
A semi flush uses about half the water that a full flush uses. This saves using water when it is not necessary to use more than is required. It saves money plus helps the environment.
Why don't we use silver electrical wires?
We don't generally use silver electrical wires because silver costs more than copper and is only marginally better as a conductor. Economics and practicality dictate our choices here. Copper is a much more common metal than silver.
Why would you use a semi-colon instead of a period explain?
Because a semi colon replaces the word "but" which means it's more complex.
