1. What is DC Voltage?

DC Voltage refers to the voltage which is unidirectional and has constant amplitude. It is the electrical potential difference that drives direct current through a circuit.

2. How Does the Calculator Work?

The calculator uses the DC Voltage formula:

Where:

• \( V \) — DC Voltage (Volts)
• \( [Mass-e] \) — Mass of electron (9.10938356×10⁻³¹ kg)
• \( Evo \) — Electron Uniform Velocity (m/s)
• \( [Charge-e] \) — Charge of electron (1.60217662×10⁻¹⁹ C)

Explanation: This formula calculates the DC voltage required to accelerate electrons to a specific uniform velocity in a vacuum space.

3. Importance of DC Voltage Calculation

Details: Accurate DC voltage calculation is crucial for designing electron beam systems, cathode ray tubes, particle accelerators, and various vacuum tube applications where precise electron velocity control is required.

4. Using the Calculator

Tips: Enter the electron uniform velocity in meters per second. The value must be positive and valid for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is electron uniform velocity?
