Parallel plate capacitor with dielectric

Charge a capacitor with a battery, then disconnect it and insert a dielectric slab. Compare C, Q, V, E and stored energy for battery-connected vs isolated capacitors and watch the charging curve.

About this experiment

What you do in the lab

Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.

Topics: capacitance · dielectric · energy · RC charging · electric field
