The quantitative electroscope is ideal for measuring the strength of an electrostatic charge. A well-balanced vane rotates in response to an electrical charge. The angle measurements printed on the back show different positions in increments of 10 degrees up to 90°. The stronger the charge the greater the deflection.
The metal case has a
