12. In-class Activity Design -2
TPS Strategy – What Instructor does
First provide a premise
What is the thermionic emission, how it is utilized in CRO and what are various elements of CRO and how can say the CRO is having negatively charged cathode.

13. In-class Activity Design -2
TPS Strategy – What Instructor does
Think (~2 minutes)
Instruction: please watch video v1 and v5 very carefully so you able to think what is the concept of behind that CRO principle.
