chargedetection
Charge detection is the measurement of electric charge carried by objects or particles, including the magnitude and sign of the charge. It plays a central role in physics experiments, electronics, and metrology, where precise knowledge of charge states is essential for interpretation, control, and safety.
Techniques used to detect charge range from simple to highly sensitive. Classic instruments include the electroscope,
Applications of charge detection span multiple fields. In fundamental physics, precise charge measurements are used to
Challenges include minimizing stray capacitance and electrical noise, preventing charge leakage, and achieving stable calibration across
