Superconductivity was first observed by the Dutch physicist Heike Kamerlingh Onnes.

He had developed a method to liquify helium and was therefore in a unique position

to perform experiments at low temperatures. In 1911, three years after his first helium liquefaction, Kamerlingh Onnes discovered that the resistance of solid Mercury

drops to zero when it is cooled below its critical temperature (4.1 K), for which he was awarded the 1913 Nobel prize of physics.

Why is it necessary to install lighting conductor in multiplex building?

Lightning conductors are installed in multiplex buildings to provide a safe path for lightning to travel down to the ground, protecting the building and its occupants from the destructive force of a lightning strike. Without a lightning conductor, there is a higher risk of damage to the building's structure, electrical systems, and potential safety hazards for occupants.


Is it good to be in the water when its lightning?

It is not safe to be in the water during a thunderstorm with lightning. Water is a good conductor of electricity, increasing the risk of being struck by lightning. It is best to seek shelter on land when there is lightning in the area.


Why does lightning strike near water?

Lightning strikes strike near water because water is a good conductor of electricity. Most lightning strikes happen by the ocean because the salt makes it an even better conductor at electricity than fresh water.


Air is the poor conductor but during lightning electric current passes through itwhy?

air becomes good conductor during lightning and thunderstorm as usually it is a bad conductor because when there is lightning the lightning bolt travel through air,an electron flow takes place. this electron flow through the air leaves behinfd it a little hollow channel in the air it produces charge and air gets charged with this and becomes good conductor during lightning and thundestorm. thanx.......... prachi singh india


What discovered that lightning on Jupiter is ten times stronger than lightning on earth?

The Juno spacecraft, a NASA mission launched in 2011, discovered that lightning on Jupiter is up to ten times stronger than lightning on Earth. This finding was revealed through data collected by Juno's Microwave Radiometer instrument during its close flybys of the planet.
