1. What is the Output Voltage Formula?

The Output Voltage formula calculates the net potential difference between the cathode and anode work functions. It represents the electrical potential difference that drives electron flow in various electronic devices and circuits.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{out} = \Phi_c - \Phi_a \]

Where:

\( V_{out} \) — Output Voltage (Volt)
\( \Phi_c \) — Cathode Work Function (Volt)
\( \Phi_a \) — Anode Work Function (Volt)

Explanation: The formula calculates the difference between the minimum energy required to release an electron from the cathode surface and the minimum energy required to remove an electron from the anode surface.

3. Importance of Output Voltage Calculation

Details: Accurate output voltage calculation is crucial for designing electronic circuits, optimizing device performance, and understanding electron flow mechanisms in various electronic components and systems.

4. Using the Calculator

Tips: Enter both cathode and anode work functions in volts. All values must be valid non-negative numbers representing the work functions in electron volts.
