A van de graaf generator is a charge pump which can generate large voltages, but at very small currents. When you connect a van de graaf to a leyden jar, the jar accumulates the energy output of the van de graaf generator and stores it up. Because the internal impedance of the leyden jar is small, it is capable of then discharging a large
Theory. The generator uses a Teflon pulley at the lower end of the machine, attached to an electric motor. A rubber belt passes over the pulley. As the pulley turns, the pulley acquires a negative charge while the inside surface of the belt near the pulley acquires an equal amount of positive charge. The outside surface of the belt acquires an

This video explains how the Van de Graaff generator works. The Van de Graaff generator generates static electricity by rubbing two insulators together. One i

At its core, a current comparator works on a simple principle. It takes two input currents, often referred to as I1 and I2. The comparator then determines which of these currents is greater. If I1 is greater than I2, the comparator outputs a certain signal, usually a ‘1’ or HIGH. Conversely, if I2 is greater than I1, the output will be
