The relationship between a cathode and an anode involves
The terminals of a diode are called the?
anode positive potential cathode negative potential
Differentiate between anode ray and cathode ray?
Anode ray is positive and cathode ray is negative
What is the purpose of an cathode and an anode in a diode?
The cathode and anode are simply two terminals of a semi-conductor junction. In a normal diode, forward bias occurs when the anode is more positive than the cathode.
What are anode and cathode streamers?
Since streamers are formed b/c of avalanche present in the gap. If the gap is small the transformation occurs only when the avalanche reach the anode and is called Cathode Streamer. If the discharge gap is quite large, over-voltages are large and hence the avalanche transfers from anode to cathode called Anode Streamer.
In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
Why anode rays also known as canal rays?
Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."
How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
Why positive rays called canal rays?
Positive rays are called canal rays because they are positively charged particles emitted by the anode and accelerated through a small canal or channel in the cathode of a cathode ray tube. These rays were discovered by Eugen Goldstein and were later studied by J.J. Thomson.
How is the formation of anode and cathode rays?
Goldstein used a gas discharge tube which had a perforated cathode. When a high electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays," which are streams of electronswhich move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode
Are anode rays emitted from anode?
There are no rays assign as anode rays (cathode rays are there in a discharge tube) but during discharge tube experiment positive rays are observed which are generated by decomposition of gaseous molecules present in the tube. X-rays are produced by striking of cathode rays with anode so x-rays may be called as anode rays.
How anode rays are formed from the gas?
Gas discharge tubes are what cause the formation of the anode rays. Several thousand bolts are put towards the cathode, which is apart of the gas discharge tubes, and the anode. This creates the anode rays.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
Which type of motion does cathode rays create?
Cathode rays create straight-line motion. They are streams of electrons that travel in a straight line from the cathode to the anode in a vacuum tube.
In the production of anode rays why perforated cathode plate is used?
A perforated cathode plate is used in the production of anode rays to allow some electrons to pass through and create a beam of electrons. This helps in generating a focused and directional electron beam for studying the properties of anode rays. The perforations also provide a way for the electrons to accelerate towards the anode, contributing to the formation of anode rays.
