Let’s learn how Van de Graaf Generator works together. The rubber bands that you see inside the device move by turning. electrical charges generated by a wire brush that rubs to the bottom of the tape are transferred to the metal ball and loaded with positive electric charge. so that the sphere is charged with high voltage. You will be observing Van de Graaf Generator and learn all about the essentials.
