Charge transfer and conservation
Two identical conducting spheres share charge when joined. Move the equalisation fraction from separated to fully connected and check the conserved total.

Electric Charges & Fields
7 free physics experiments and lesson notes for Electric Charges & Fields, with model limits, worked examples and Tamil explanations.
Coulomb force
Change signs to switch attraction and repulsion. Increase separation to see the force decrease with the square of distance. Positive force here means repulsion.
Run this experiment →Superposition and charged ring
Point-charge vectors add component by component. A uniformly charged ring is the continuous limit: transverse components cancel on its axis. Select both sources to compare.
Run this experiment →Point-charge field and field lines
A positive test charge defines field direction. Positive sources have outward radial fields; negative sources have inward fields. The graph records that signed radial direction.
Run this experiment →Electric dipole field and torque
Compare axial and equatorial fields and rotate a dipole in a uniform external field. The field falls as r⁻³ in the far-field approximation.
Run this experiment →Electric flux and Gauss law
Tilt an open surface to change its projected area. Closed-surface flux instead depends on net enclosed charge; external charges contribute zero net closed flux.
Run this experiment →Gaussian wire, sheet and shell
Switch the charge geometry. A wire gives a 1/r field, an ideal sheet gives a distance-independent field, and a shell gives zero interior field.
