# Resistance of human body

Objective

Measure the resistance of human body by comparing it with a known resistor. We start with a DC input from PV1 and then using the AC signal from WG.

Procedure

- Set PV1 to 3 volts

- Join PV1 and A2, through your body and measure voltage at A2

- Calculate your body’s resistance, as given in section 2.4↑

- Repeat using SINE instead of PV1. Enable analysis on A1 and A2 to measure voltage.

Discussion

The DC measurements are affected more by the electrical noise. The AC resistance should be less than the DC resistance. The resistance is due to our skin and AC can pass through this, like it passes through a capacitor.
