1. What is Deflection on Screen?

Deflection on Screen refers to the movement or displacement of the electron beam on the screen. In an oscilloscope, the electron beam is used to create a visual representation of electrical signals.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: This formula calculates the deflection distance on the screen based on the deflection sensitivity and the applied electric potential difference.

3. Importance of Deflection Calculation

Details: Accurate deflection calculation is crucial for proper calibration of cathode-ray tubes and oscilloscopes, ensuring accurate visual representation of electrical signals.

4. Using the Calculator

Tips: Enter deflection sensitivity in m/V and electric potential difference in V. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is deflection sensitivity?
A: 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.

Q2: What units are used for deflection calculation?
A: Deflection is typically measured in meters (m), deflection sensitivity in meters per volt (m/V), and electric potential difference in volts (V).

Q3: Where is this calculation commonly used?
A: This calculation is primarily used in cathode-ray tubes, oscilloscopes, and other electron beam display devices.

Q4: What factors can affect deflection accuracy?
A: Factors include magnetic field interference, temperature variations, component aging, and power supply stability.

Q5: How does electric potential difference affect deflection?
A: Higher electric potential difference results in greater deflection of the electron beam, producing larger displacements on the screen.
