The potential difference in a circuit is what causes current to flow through the circuit. The larger the potential difference, the faster the current will flow and the higher the current. The potential difference is the measure of the difference in voltage between two distinct points in a closed...
That is the grace of the law of energy conservation. As a result, there is an imbalance of charges between the two materials, which can be thought of as potential energy. In other words, the energy you spend to rub the materials becomes electric potential energy in the end. Voltage, whi...
