A Study of Visualizing the Characteristic of Capacitor and Gauss‘s Law by using LED

We suggest a new method to visualize the characteristic of capacitors and Gauss’s Law. We did experiments to confirm that the LED can visualize the electric field. And Based on these, we did experiments about various properties of capacitor and Gauss’s law by the intensity of LED’s light in capacitor. In conclusion, we have shown that LED light can show …
