This technical assistance paper was developed to clarify specially designed instruction, core instruction and interventions within a multi-tiered system of supports (MTSS) for. educators developing, improving and maintaining systems of support for all students.
The charge of the electron is about -1.60217733 x 10-19 C, the charge of the proton is equal and opposite to that of the electron, both charges are constant.
1 Electron was discovered by J. J. Thomson in Cathode Ray Tube (CRT) experiment. 2  Electrons are negatively charged particles with charge-to-mass ratio \(-1.76Ã10^8\) C/gm. 3  The charge of an electron was measured by R. Millikan in Oil drop experiment.igure 4. Robert Millikan discovered charge of electron and won Noble prize in physics in 1923. In 1909, American physicist R. Millikan measured the charge of an electron using negatively charged oil droplets. The measured charge (e) of an electron is \(-1.60Ã10^{-19}\) Coulombs.
