why it is necessary to decrease the pressure in the discharge tubbe to get cathode rays
The anod terminal of diode is connected with negative and cathod is connected to positive
In ceramic capacitors if you observe it then one of its terminal is smaller than other one.Thus,the longest one is its anode and other one is its cathode.
Cathode rays have momentum that allows them to cause the paddle wheel to rotate as they collude with its paddles. The rotation is a result of the force exerted by the moving particles.
Cathode rays are streams of electrons.
sir jj thomsons was a brialiant english physics scientist, he observed the cathod in atom, later called electron, by CRT CATHOD RAY TUBE
CRT Cathod ray tube
for
capacitor storage the charge by the two plattes anode cathod & now insulater bettewen them.
The anod terminal of diode is connected with negative and cathod is connected to positive
LCD stands for Liquid Crystal Display and CRT stands for Cathod Ray Tube
J. J. Thomson observed that cathod rays are deflected by an electric field - and from this discovered the electron.
there are two type of monitor namely : "cathod ray tube(CRT)" , " Liquid crystal display (LCD)" newtest3
J. J. Thomson observed that cathod rays are deflected by an electric field - and from this discovered the electron.
The various display units available in market are cathod ray tube, light emitting diodes,neonplasma devices etc
