How to Work Safely with Electricity in the Laboratory

This 1 minute safety training video covers: What are the problems electricity can cause, what is the possible result of performing improper equipment maintenance or adjustments, how electrical current is measured, what is the difference between volts and current, how intensity of the current is measured, what are causes of electrical shocks.

The flow of electrons through a conductor is called current. Current is created whenever there’s a source of free electrons of negative charge and one end up of conductor and a deficit of electrons or a positive charge at the other end to attract the electrons. Current is measured by the amount of charge attributed to electrons flowing past a given point each second this measurements is express in amperes or amps. When free electrons creating a negative charge gather in one place and are depleted on another causing a positive charge and there’s a conductive path between the two. The electron will attract to the positive charge until the charge is balance each other. If you were to compare voltage to current using the water flow model current will be a certain amount of water flowing pass to a specified point in a second, voltage would be considered the force that makes it flow.
