Calculate electric vehicle battery voltage by multiplying the number of cells by nominal cell voltage. Essential tool for EV battery management.
Electron-volts (eV) and volts (V) are both key concepts in electrical physics. While eV measures energy, volts refer to electric potential. You can convert eV to V by dividing energy by the charge. For example, if you have 1 eV and a charge of 1.602×10⁻¹⁹ C (elementary charge), the potential difference is 1 volt. This calculator simplifies that process for practical uses like electronics, circuits, or quantum mechanics.
Formula 1 (using charge in C):Volts (V) = eV / Q
where Q is charge in coulombs.
Formula 2 (using elementary charge):Volts (V) = eV / (n × e)
where n = number of electrons, e = 1.602×10⁻¹⁹ C.
These formulas apply when calculating electrical potential from energy and charge.
Convert electron-volts (eV) to volts (V) by dividing eV by the charge in coulombs. This calculator helps convert electric energy into potential difference easily.
| eV (Electron-Volts) | Charge (C) | Voltage (V) |
|---|---|---|
| 1 | 1.602×10⁻¹⁹ | 1 |
| 5 | 3.204×10⁻¹⁹ | 15.6 |
| 10 | 5.0×10⁻¹⁹ | 20 |
