Why do power plants produce AC power naturally?
AC (alternating current) is the primary form of electricity because it can be generated at very high voltages and sent across many, many miles of carrying lines.
Why is the national grid system better than each town having its own supply?
Because then every town has the same voltage: before, if there was a sudden demand for electricity in one town- nearby towns couldn't help for they had different voltages. So, the town couldn't cope with the electricity demand but now it can because of the National Grid.
What is a micro voltmeter?
A microvoltmeter is a type of voltmeter with special calibration. This special calibration allows it to show the values of voltages in microvolts.
What is Nikola Tesla background?
From the time he was a child, Tesla was always considered eccentric. Shortly after his graduation from high school, Tesla suffered a devastating bout with cholera and nearly died. He was bedridden for nine months, and doctors announced that he would not live much longer. Tesla asserted that it was not until he reached adulthood that he discovered he was an inventor. Tesla began his college education at Graz Polytechnic Institute, pursuing studies of the topic that fascinated him above all others: electricity. The 'Tesla Coil' is a device invented by him. It is a high voltage, high frequency, power generator, primarily built for conducting experiments and to observe phenomenon associated with alternating electricity. With this coil, Tesla was able to generate voltages of such magnitude; they would shoot out of the apparatus as bolts of lightning. He wanted everyone to have electricity for free. That didn't work for the money makers of the day. The invention he is most known for is the ac electricity system which the whole world uses to light houses and other buildings.
What is the voltage that comes out of power stations?
Let's look at this from a from a simplistic point of view. When working with electricity, power is a combination of amperage, and voltage. Amperage drops significantly with distance, voltage does not. Because of this, a power plant generates its power as a combination of a huge voltage with very little amperage. Therefore, the power loss over long distances is minimized. Power station voltages are in the hundreds of thousands of volts. However, these voltages are too dangerous for everyday use. Thus, they are transformed down to lower voltages such as 120 for household use, 480 for industrial, and other voltages. During power transformation, power is not lost. Thus, if you decrease the voltage, then your amperage goes up to provide the same power.
What are the Advantages and disadvantages of rectifiers?
There are different types of rectifiers including silicon controlled rectifiers. Advantages for this type of rectifier include that it can switch high voltages and is simple to control. Disadvantages include it cannot be turned off easily.
What are the advantages and disadvantages of piezoelectric sensors?
Advantages:- They generate a voltage proportional to the velocity the crystal is deformed so require no local power source. Disadvantages;- They are high impedence and can pick up stray voltages in the connecting wires. The crystal is also prone to cracking if overstressed
Can electricity tickle?
Yes, at low voltages.
What are grounding mats used for?
Grounding mats are used when working on electronic components to drain off static electricity. Static electricity develops high voltages (the spark that jumps from your hand to a doorknob in winter is static electricity) and these voltages can damage sensitive electronics.
What are Advantage and disadvantage of spst switch?
Advantages: Low cost Reliable Able to function with high voltages and currents Disadvantages The label could wear off after being used for a long time, create confusion for the user
Where does electricity work efficiently?
A transformer is one place where electricity is very efficient in changing AC voltages from one level to another.
Does electricity help your body to work?
Yes, electricity does help your body to work! Your brain sends and receives electric messages to and from all the parts of your body. That is what makes you move, talk, run... you name it! But the voltages are not very high! High voltages can kill you!
How much voltz is current electricity?
Voltages used vary from 1.5 v to 750,000 volts.
How far can electricity travel through air at different voltages?
20KV can throw a spark about a centimeter long in dry air. the distance at other voltages is directly proportional to the voltage. you should be able to calculate the distances for other voltages yourself from this info.
What are the answers for transmissions an distributions of electricity?
electrisity leaves the power plant and is transformed for a long distance at voltages
Why do some electrolytes give better voltages than others?
because they re-act better to electricity
How many volts of electricity are used by an average person a day?
In North America we use 120/240 voltages for residences. 120/208 is used in smaller businesses and 240,277,347,480,600 voltages are used in industries. Directly and indirectly people use these voltages every day.
