Who invented amperes?

Nobody. They have been around as long as lightning strikes. There are no ampheres unless voltage is present and moved through a circuit. Who named it? Amphere maybe. ?


What is power frequency withstand voltage test?

A test done on a transformer. The voltage at the power frequency is ramped up to verify the transformer is capable of handling the stresses due to switching and natural phenomena (lighting strikes).Withstand Voltage:The voltage which has to be applied to a test object under specified conditions in a "withstand test" is called the "withstand voltage".


Why does the electricity go out when it is storming?

Storm related electrical outages may occur for a variety of reasons, most of which are caused by lightning strikes, fallen trees, or weather related damage to the components of the electrical system. If a major storm produces severe flooding, the local electrical power may be turned off to prevent accidental electrocution and to prevent damage to the main electrical grid infrastructure.


How much power is 4 MW?

4 megawatts - heaps The megawatt is equal to one million watts. Many events or machines produce or sustain the conversion of energy on this scale. For example: lightning strikes, large electric motors, naval craft (such as aircraft carriers and submarines), engineering hardware, and some scientific research equipment, such as supercolliders and large lasers. A large residential or commercial building may consume several megawatts in electric power and heat.


What are the round ball like structure on the topmost line in power transmission lines?

The topmost conductor in a transmission line is called the guard conductor; it is an earthed (grounded) conductor that links the metal support towers. Its function is to protect the transmission lines against lightning strikes. The coloured balls that are sometimes seen distributed along the guard conductor are intended to make the lines easier to see in those areas where aeroplanes might be flying -they are often seen on lines in the vicinity of airfields. They are also used in areas, such as nature reserves, to make the lines visible to large birds.

In a photocell light energy is converted into?

In a photocell, light energy is converted into electrical energy. When light strikes the photocell surface, photons of light are absorbed, releasing electrons that create an electric current.


What type of material is a photocell made from?

A photocell is typically made from a semiconductor material such as silicon. When light strikes the semiconductor material, it generates an electric current, making it a key component in light-sensing devices.

Why was there a steady increase in the number of strikes during the 1830?

The increase in strikes during the 1830s was due to a combination of factors, including poor working conditions, low wages, and the growth of industrialization. Workers were increasingly organized in trade unions and became more vocal in demanding better rights and working conditions, leading to a rise in labor unrest and strikes.

How does gravity make it easier to hammer a nail?

Gravity helps to increase the force with which the hammer strikes the nail, making it easier to drive the nail into the surface. Gravity pulls the hammer downward, increasing its velocity and impact force, which helps to overcome the resistance of the nail and drive it into the material.
