The grid in a high vacuum triode is usually kept negatively charged with respect to the cathode so that the electrons may be?

A grid in a high-vacuum triode is usually kept negatively charged with respect to the cathode so that the electrons may be passed through to the anode, but controlled by changes in grid voltage. The triode accomplishes this by amplifying signals applied. ...

A grid in a high vacuum triode is usually kept negatively charged with respect to the cathode so that the electrons may be attracted to the anode instead of the grid. The triode was invented by Lee De Forest in 1906 and is considered as the first electronic amplification device. ...

attracted to the anode instead of the grid

So that the electrons may be controlled. The idea is to let only a fraction of them through to the anode, and the amount is controlled by the grid voltage. If all the electrons that came from the cathode got through, the grid would have no effect and the triode would be useless. ...

the grid is negative so it can control the amount of electrons coming off the cathode. To stop or decrease intensity of cathode ray/electron beam, it is made more negative (to repel electrons as negative charge and negative charge repel) and to increase intensity, the grid is made less negative. ...

attracted to the anode instead of the grid

C C doesn't help at all, i don't know if you didn't notice but the question and answers got all switched around the answer is- attracted to the anode instead of the grid ...

If this is for your Penn-foster test i can tell you one thing is that the the answer isn't "accelerated toward the anode". ...

A body is charged when it exchanges some electrons and develops a potential with respect to zero potential at infinity. ...

a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge. ...

Electrochemical Cells Corrosion is electrochemical in nature because the corrosive chemical reactions involve transfer of charge. Iron goes into solution as Fe++ ions. As these ions go into solution, the metal becomes negatively charged (by the electrons left behind) with respect to the electrolyte. ...

The cathode must be made more positive with respect to the anode.

it is not necessary that always positive voltage should act as a forward bias voltage , it is the potential difference between cathode and anode that makes it forward or reverse biased . it the anode(p- doped material) positive with respect to cathode(n- doped material) --> forward biased it the anode(p- doped material) negative with respect to cathode(n- doped material) --> reverse biased ex. anode - 5v cathode - 3v anode - 1v cathode - -2v both the examples are forward biased. ...

The cell membrane is semi-permeable so that charged ions can not diffuse down or up a concentration cell into or out of the cell. There are cell bound proteins that transport charged ions like K+, Na+ and Ca2+ across the cell membrane and the net effect is that the cell is negatively charged ( about -70 mV) with respect to the extracellular space. ...

It's any charged particle (electron, proton and so on) which is at rest with respect to the predefined reference frame. ...

Neutrons have no charge. They are neutral, with respect to electrical charge. ...

The electron beam produced in the cathode is essentially negative (with respect to the anode), therefore it tends to go towards potentials above the cathode's potential (more positive or less negative, as you wish). ...

The anode is the arrow shaped end, while the cathode is the bar shaped end. You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention. The exception, of course, is the zener diode, where current flows in both directions, but at different potentials. In this case, there are two 45...

Elements in group 1 have a lower number of electrons with respect to the other elements in the same period. ...

A forward-biased diode has a positive DC on its anode with respect to its cathode. ...

Usually, metallic elements have a lower number of valence electrons with respect to the non metal elements in the same period. ...

The true direction of the flowing particles depends on the type of conductor. Teachers promote idea that electric current is a flow of positive particles in one direction, when supposedly it's a flow of negative electrons going the other way. Electrons flow from the anode to the cathode. The cathode is usually, but not always, the negative end. Comment For metallic conductors, an electric current is an extremely slow drift of free electrons from the negatively-charged end to the positively-charged end of that conductor. However, many...

In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element. ...

A: An scr is a 4 layer diode and has 3 terminals gate anode and cathode. To turn it on the gate must be positive with respect to the cathode and have enough voltage and current to turn it on. The turn on also depends on the load. Another possibility is to increase the potential cathode to anode until it will turn on but this mode is not predictable. Once on there only two way to shut it off. Remove to...
