1. What is Deflection Sensitivity?

Deflection Sensitivity is the displacement of the electron beam at the target or screen of a cathode-ray tube per unit of change in the deflection field. It is a crucial parameter in devices like oscilloscopes and cathode-ray tubes.

2. How Does the Calculator Work?

The calculator uses the Deflection Sensitivity formula:

Where:

• \( S \) — Deflection Sensitivity (m/V)
• \( D \) — Deflection on Screen (m)
• \( V_d \) — Electric Potential Difference (V)

Explanation: The formula calculates the sensitivity of the electron beam deflection in response to changes in the electric potential difference.

3. Importance of Deflection Sensitivity

Details: Accurate calculation of deflection sensitivity is essential for designing and calibrating cathode-ray tubes and oscilloscopes, ensuring precise measurement and display of electrical signals.

4. Using the Calculator

Tips: Enter deflection on screen in meters and electric potential difference in volts. All values must be valid (deflection > 0, potential > 0).

5. Frequently Asked Questions (FAQ)

Q1: What units are used for deflection sensitivity?
A: Deflection sensitivity is typically measured in meters per volt (m/V).

Q2: How does deflection sensitivity affect display quality?
A: Higher deflection sensitivity means the electron beam moves more for a given voltage change, which can affect the precision and accuracy of the displayed signal.

Q3: Can this formula be used for all types of cathode-ray tubes?
A: The basic principle applies to most cathode-ray tubes, but specific designs may require additional factors or calibration.

Q4: What is a typical range for deflection sensitivity?
A: Deflection sensitivity values vary widely depending on the device, but common ranges are from 0.1 to 10 m/V.

Q5: How is deflection sensitivity measured experimentally?
A: It can be measured by applying known potential differences and measuring the resulting deflection on the screen, then calculating the ratio.
