A cathode ray tube (CRT) emits light when electrons strike the front of the glass tube that is covered in a phosphor coating. The front of the tube is the anode of the tube. The electrons are fired from the rear of the tube by an electrode called the cathode.
The electrons are formed into a beam or ray, hence the name of cathode ray tube.
Although the electrons travel from the rear of the tube to the front, or from the cathode to the anode, conventional current actually flows the opposite direction. So, the current, as measured in amps will flow from the anode to the cathode.

Is the picture tube a conductor or an insulator Explain your answer?
A picture tube is an insulator. The electrons would gather up and so, create an electric charge when the TV is on. If it was a conductor, the charge would not build up. Hope this helps :)
