##### Reference no: EM13247260

Two straight wire-electrodes are placed, in parallel, across your index finger a distance 2.50 cm apart. The terminals of a battery, with a voltage of 8.20 V, are attached, one to each electrode. If an ammeter in series with the electrodes displays a current of 0.760 µA, what is the resistance of your skin?

The width of the contact of each wire with your skin is 1.10 cm and the thickness of the conducting layer of your skin is 0.023 mm.
Assuming that these two dimensions define an area through which the current flows, calculate the resistivity of your skin.
