## Schematic

- Electrical resistance of human body can be safely measured using the low voltage signal from ExpEYES..

## Instructions

- Connect the wires and resistors as shown in the figure. Set PV1 to 3 volts

- Hold the tip of the wires, marked as 'hand', tightly by two hands

- Current through the 100K resistor I = A2 / 100K

- Electrical resistance of your body is given by (A1-A2)/I

- Perform the same experiment using AC from WG instead of the DC from PV1.

- The resistance is mainly due to the skin. With AC, skin acts as the dielectric of a capacitor. Due to it more current flows, for a given AC voltage, compared to DC.
