What is electric discharge class 9?

What is electric discharge in short answer?

Electric discharge is defined as the process of the release and transfer of electricity in an applied electric field through any possible medium. Usually, electric discharge is made to occur through a gas or the atmospheric air.

What is electric discharge Ncert?

discharge of electric charges through our body, which were accumulated. due to rubbing of insulating surfaces. You might have also heard that. this is due to generation of static electricity.

What is electric discharge give an example?

Electric discharge denotes the excitation of atomic states in a gaseous medium on passing an electric current through the medium. An ordinary household fluorescent lamp is an example of an electric-discharge source.

What is an electrical discharge called?

An electric discharge is the release and transmission of electricity in an applied electric field through a medium such as a gas. … As the charge on these particles builds up, the result is the often-spectacular discharge of electricity known as lightning.

What is electric discharge how it occurs?

Answer Expert Verified

Electric discharge refers to the flow of electricity or electric charge through a medium. The medium may be a solid, a liquid or a gas. When two points of different electrical potential make contact in the medium in which they are placed, it causes an electric discharge.

What is electric discharge class 8?

Answer: When negative and positive charges meet, producing streaks of bright light and sound. This process is called an electric discharge. When the accumulation of charges between lower part of clouds and earth becomes large, it is sufficient to break the insulation of air.

What is electric field intensity?

A measure of the force exerted by one charged body on another. Imaginary lines of force or electric field lines originate (by convention) on positive charges and terminate on negative charges.

What is Earth’s plates Class 8?

The outer layer of the earth is fragmented. Each fragment is called a plate. Earth’s plates are in continualen these plates brush ptone another or undergo collision, causes earthquakes.

What is negative charge Class 8?

When an object has more electrons than protons then the object is said to be negatively charged. Similarly, when an object has more protons than electrons, the object is said to be positiely charged.

Which is the high electric discharge?

For instance, high voltage electric discharge (HVED) disrupts cell tissues in liquid samples and subsequently enhances extraction of valuable compounds from plant food materials and by-products.

What is the power of discharge?

In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.

What is electric force?

Electric force is the attractive force between the electrons and the nucleus. … It works the same way for a negative charge, you also have an electric field around it. Now, like charges repel each other and opposite charges attract.

Is lightning an electric discharge?

Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds.

Who discovered electric discharge?

In the late 1830s, Michael Faraday’s experiments on electrical discharge in attenuated gases gave a new prominence to the subject. Over several decades these discoveries served to stimulate critical investigations at home and on the Continent, notably in Germany.

What happens when electricity passes through helium?

When an electric current is passed through a gas, the gas emits light. This emission is exploited in many electric lamps. … The identity of the gas in the tube determines the color of the glow. Neon emits a red glow, helium produces pale yellow, and argon yields blue.
