Einstellbarer Hochspannungswiderstand

The resistor has a pressure chamber (6) that is provided to adjust the pressure of a variable fluid. Two electrodes (1) are arranged inside the pressure chamber, such that the electricity causing voltage is controlled between the electrodes. The electrodes are fixed in an operating distance, such that the corona and/or spark are discharged between electrodes upon application of voltage in a range of values of the pressure adjusted in pressure chamber for causing the current between electrodes. Independent claims are included for the following: (1) a potential divider; (2) an electrostatic coating apparatus; and (3) a method for controlling current between electrodes of adjustable high voltage resistor.
