Question

Vidicon works on the principle of:

• A. Electrical conductivity
• B. Photoconductivity
• C. Thermal conductivity
• D. SONAR

Hint:

Vidicon cameras use photoconductivity to convert light into an electrical signal for video recording.

Answer 1

The Correct Option is B

Step 1: Understanding Vidicon. Vidicon is a type of video camera tube that works based on photoconductivity. It converts light into an electrical signal by changing the conductivity of a semiconductor in response to light.
Step 2: Conclusion. Thus, Vidicon operates on the principle of photoconductivity.
