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.

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

What sub atomic particle is a cathode ray?
Electrons--the cathode is negatively charged, the anode is positively charged.
Why cathode rays are negatively charged?
Cathode rays are produced when the metal cathode has a high voltage applied to it - this has the effect of "boiling" the electrons off the cathode's surface producing cathode rays, and so cathode rays can be seen as a stream of electrons i.e. negatively charged particles.AnswerElectrons are released from the surface of a cathode through thermionic emission. This is achieved by a heaterlocated at the cathode, and not due to a high voltage. The function of the high voltage (between the cathode and an anode placed closer to the screen) is to attract these electrons towards the screen of the CRT. So a 'cathode ray' is simply a beam of electrons which, of course, are negatively charged.
What is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
What does a cathode ray consists of?
No, a cathode ray tube consists of a stream of electrons.
What effect will a positively charged metal plate have on a cathode ray?
Since a cathode ray is a stream of electrons, and since electrons are negatively charged, a positively charged metal plate would cause a deflection in the cathode ray towards the plate.
Who discovered negatively charged electrons using a cathode ray tube?
JJ Thomson.
How are cathode charged?
negatively charged
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
What are the role of cathode tubes in atom?
cathode tubes were used to detect the particle in an atom & found that negatively charged particles(electrons) are there in an atom.
How do negatively charged plates affect the path of cathode rays?
negatively charged plates affect the path of cathode rays by repealing the cathode rays.
Why did j.j reason the electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
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
