# Human body as a conductor

Objective

Touching the AC mains is fatal to us because our body is a conductor. We can explore this using low voltage signals.

Procedure

- Set WG to 200 Hz.

- Enable A1, A2 with analysis enabled.

- Conenct WG and A1, with a wire

- Connect WG and A2 through your body and note voltages

- Repeat it using a 3 volt DC signal from PV1.

Discussion

The observed peak voltage will be less than 3volts, due to the resistance of the body. There could be some ripple due to the 50Hz AC pickup. This can be eliminated by performing the experiment far away from power lines, using a laptop.
