Question

Precautions for electric conductivity of liquids

Answer 1

Injuries caused by electricity include electrical shock, burns, and falls due to electrical shocks and burns. Electrocution is a fatal electrical shock. Electrical shock occurs when current passes through the body. The severity of the shock depends on:

Amount of current flowing through the body,

Path of current through the body,

Length of time the body is in the circuit.

Note: Low voltage or low current does NOT mean low hazard! Less than 10 milliampere can cause a painful shock and loss of muscular control, and 50 milliampere can be fatal (see the table below for more details). 

Electricity seeks all paths and not just the path of least resistance to reach lower potential

Answer 2

Precautions to be followed while testing the electrical conductivity of liquids:

• see that the two metal pins or electrodes do not touch each other.

• Make sure the two pins or electrodes are in contact with the solution.

• After testing each liquid, wipe or dry the pins or electrodes.
