Exploring the physiological effects of electrical currents William accidentally sticks a pair of scissors into the active terminal of a 230V general purpose outlet (GPO) while holding on to a water tap. Current from active conductor, through operator, and returned through metal tie Current will flow from the GPO active terminal through William to ground (via the tap) causing a physiological response. In this exercise we will approximate skin impedance by skin resistance for simplicity. Part 1: Is this is macroshock or microshock? Part 2: Using the resistance values for wet and dry resistance for "hand holding wire" as noted in Webinar 1, calculate: a) With wet hands how much current will flow through William's body at each end of the resistance range? b) With dry hands how much current will flow through William's body at each end of the resistance range? Part 3: Using the graph of physiological effects of electrical currents in Webinar 1, describe the physiological effects at the low and high end of the range for wet hands and the physiological effects at the low and high end of the range for dry hands
