Question

State the approximate potential difference applied between the anode and filament cathode ray tube .

• A. 1000 V
• B. 50 V
  
• C. 5 V
  
• D. 1 V
  

Answer 1

The correct option is A 1000 V

The electrons are accelerated by a second anode at high potential, more than 500 V.

So, the answer is option (A).
