- 2. What is the capacitive reactance of a 0.10 µF capacitor at a 100HZ audio frequency and at a 100MHZ FM-radio frequency?Please AsApThink about the rms current through a person if they touch a 120 Vrms AC source in the following conditions: 1. Standing on a rubber mat which offers a total resistance of 275 kÖ in mA. 2. Standing barefoot on wet grass and has a resistance of only 3800 2 in mA. Neither is a good option but which would be the worst option? meaning which would have the Largest rms current? Both have the same rms current Standing on a rubber mat which offers a total resistance of 275 k in mA. Standing barefoot on wet grass and has a resistance of only 3800 Q in mA.
