Question

a) how do ionizers, radioactive neutralizers and antistatic materials work?why does humidification work?

b) using Ohms law,(V=IR) estimate which of the following combinations of skin conditions and voltage sources (1a, 1b,.....,4d/16 combination total) would produce a shock strong enough to potentially stop the heart ( current > 100mA)

1) dry hands (resistance ~ 25 k ohms a. A 9- V energizer battery

2) wet hands ( resistance ~ 2.5 k ohms) b. A 12-V car battery

3) hands immersed in liquid ( 1000 ohms) c. an 18-V cordless drill battery   

4) open wound in the skin ( 100 ohms ) A d. 110- V household outlet   

c) using Ohm's law, how much current would you expect a person (10,000 ohms of skin resistance) to receive ( and what physiological impact would it have) if they became part of a 110-volt circuit in parallel with an incandescent bulb (400 ohms)

Explanation / Answer

a) The ionizers ionizes the air surrounding a charged surface to provide a conductive path for the flow of electrons. This is carriedout by using a device to create to create positive and negative ions and distributing them across an insulated box.

The radioactive neutralizers contais radioactive elements that fubctions by emiting positive charged particles which can be able to neutralize collected negative electrical charges.

The antistatic materials functions by increasing the surface conductivity of charged material or by absorbing moisture, which further reduces the resistance and accumulate the charge. These materials are effectively used to reduce electrical static hazards.

Humidification is the process with a purpose of reducing the electrical static condition. Maintaining the humidity level at or above 65% reduces charge accumulation.
