1. What is an Applied Potential Calculator?

Definition: This calculator determines the applied potential in potentiometry based on cell potential, current, and resistance.

Purpose: It helps electrochemists and researchers calculate the required potential to be applied in potentiometric measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{app} \) — Applied potential (volts)
• \( E_{cell} \) — Cell potential (volts)
• \( I_P \) — Current (amperes)
• \( R_P \) — Resistance (ohms)

Explanation: The applied potential is the sum of the cell potential and the product of current and resistance in the circuit.

3. Importance of Applied Potential Calculation

Details: Accurate applied potential calculation ensures proper potentiometric measurements, which are crucial in analytical chemistry and electrochemistry.

4. Using the Calculator

Tips: Enter the cell potential in volts, current in amperes, and resistance in ohms. All values are required for the calculation.
