Weband floating, the DMM still reads a voltage. The higher impedance isn’t sufficient to eliminate these ghost voltages, but a low impedance provides a path for this built-up charge and allows the DMM to correctly measure 0 V. An example of this at a lower voltage range is if you had traces close together on a circuit. b. Crest Factor Web23 okt. 2013 · Yes it does. The lower the collector current the smaller the effect of the collector impedance and consequently a lower collector emitter voltage.
