What is a arc?
discharge: electrical conduction through a gas in an applied electric field
What is atmospheric discharge?
An atmospheric pressure discharge is an electrical discharge in air at atmospheric pressure.An electrical discharge is a plasma, which is an ionized gas. Plasmas are sustained if there is a continuous source of energy to maintain the required degree of ionization and overcome the recombination events that lead to extinction of the discharge. Recombination events are proportional to collisions between molecules and thus to the pressure of the gas. Atmospheric discharges are thus difficult to maintain as they require a large amount of energy.Typical atmospheric discharges are:DC arcLightningAtmospheric Pressure Glow Discharge (APGD)Dielectric Barrier Discharge (DBD)love.....razor
What gas is obtained by fractional distillation?
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
What are the properties of xenon?
Xenon normally is a colorless gas, but it emits a blue glow when excited by an electrical discharge
How a gas is ionized?
For example applying an electrical discharge, a very high temperature or by irradiation with ionizing radiations.
What are the three components in a gas discharge lamp system?
A gas discharge lamp has a gas and has a cathode, an anode, and an ignition electrode. Individual discharges of a series of lamp discharges are spaced at least one millisecond from each other, and the individual discharges are generated by providing an electrical charge between the cathode and the anode and providing two or more electrical pulses to the ignition electrode. The second and following electrical pulses occur within a predetermined time of the first pulse. The electrical charge between the cathode and anode is of sufficient voltage and current to create an electrical arc between the cathode and the anode with the gas is ionized.
How is electrical energy changed to light energy in a circuit?
Either by the current heating a fine wire until it glows in the incandescent lamp, by an electrical discharge exciting agas or flourescent material in gas-discharge and flourescent lapms respectively, or by a quantum effect in the light-emitting diode.
Which is a good example of a gas at normal room temperature Gold Lightning Oxygen or Water?
Oxygen is a gas at room temperature. Gold is a solid, water is a liquid, and lightning is an electrical discharge.
Why crook tube is called discharge tube?
If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.
State the products obtained when candle is burned.?
Carbon dioxide (gas) and water (vapor) from fat or wax (solid) and oxygen (gas, from air)
Where is neon mined?
Neon is a gas so it actually can not be mined. It is actually obtained by fractional distillation of Air.
Why electrical discharge pumping is used in helium neon laser?
because of gas in active center Neon gas worked as Active Center for He-Ne laser.to accelerate the Ne atoms very high and efficient Pumping is required. Which can only be given by Electric Discharge Pumping.
