our body is a moderately good conductor of electricity. Taken as a whole, your body's resistance measured for conduction from the fingers of one hand to the other is about 1500 ohms when the body is dry and typically 500 ohms when wet. The electric potential at a wall socket is 120 volts, so if you touch a high-potential house wire with one hand and ground with the other, the current through your body (dry) is approximately

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.
