Determining Specific Charge of Electron

This electron charge-to-mass ratio and thermionic emission experiment system is designed to investigate the fundamental properties of electrons through thermionic emission and magnetic field control. It enables students to determine the work function of metals, measure the electron charge-to-mass ratio (e/m), study the Fermi-Dirac distribution, and determine the Fermi energy level. The system includes computer-based data processing for accurate analysis and advanced laboratory experiments. Physics Lab Experiments from Atico Exports.
