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.

Cathode rays were shown to be a stream of?

Cathode rays are electrons.

Stream of particles originating from a cathode?

Those are electrons.

Difference between direct and indirect cathode ray?

In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.

In the cathode ray tube where do the particles originate?

In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.

What is the charge of the particle in cathode rays?

The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.

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.
