Question

Figure below shows some of the important features of a cathode ray tube.

What does 'S' and 'T' represent in the diagram?

• A. ‘S’ is Cathode which accelerates electrons and ‘T’ is Anode which generates electrons
• B. ‘S’ is anode which accelerates electrons and ‘T’ is cathode which generates electron
• C. ‘S’ is Cathode which generates electrons and ‘T’ is Anode which accelerates electrons
• D. ‘S’ is anode which generates electrons and ‘T’ is cathode which accelerates electrons

Answer 1

The correct option is C

‘S’ is Cathode which generates electrons and ‘T’ is Anode which accelerates electrons

‘S’ is Cathode which generates electrons by Thermionic emission and ‘T’ is Anode which accelerates electrons due to a strong electric field.
