Complete Table 4.8.
Cathode-Ray Tube Describe a cathode-ray tube andhow it operates.
Electricity travels from the cathode to anode.
this rate shows the general flow of electrons. So we hear we have a beam which moves thes positive, charged elections all the way over Tricky. And I am It shows the transfer of electrons.
