At low frequencies parasitic capacitance can usually be ignored, but in high frequency circuits it can be a major problem. In amplifier circuits with extended frequency response, parasitic capacitance between the output and the input can act as a feedback path, causing the circuit to oscillate at high frequency. These unwanted oscillations are called parasitic oscillations. Web26 Sep 2014 · Stray currents are typically seen in larger motors—above 444T—and poorly grounded systems, though they have been observed in all sizes of motors and applications. The current has several options when traveling to the ground, either through the motor bearings or other equipment bearings. This means that the motor does not always fail.
