WebThe crucial difference between resistance and reactance is that resistance is the hindrance to the flow of electric current by only resistor. As against reactance is the opposition to the change in current by either inductor or capacitor. Basically, the obstruction to the flow of electrical current in any circuit is defined as impedance. WebA dv/dt Filter, installed in front of the motor, combines the current limiting ability of an AC line reactor plus a resistive (and/or capacitive) circuit that forms a damped, low pass filter. It provides protection for the motor by slowing the rate of voltage increase and minimizing the peak voltage that occurs at the motor terminals.
