Find the current through a person and identify the likely effect on her if she touches a 120 V AC source in the following circumstances. (Note that currents above 10 mA lead to involuntarily muscle contraction.) a) Find the current (in mA) if she is standing on a rubber mat and offers a total resistance of 305 kΩ. b) Find the current (in mA) if she is standing barefoot on wet grass and has a resistance of only 3500 Ω
