Resistance.
The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.

A wider wire has lower electrical resistance, allowing for more current to flow through. This is because there is more cross-sectional area for the electrons to flow, resulting in less obstruction to the flow of current. Thus, as wire width increases, the current carrying capacity also increases.
An electrical charge is the result of the flow of electrons.
Asphyxiation
Electrical conductors.
Electrical charges will not flow. The considered to be held stationary.
A flow of electrical charges running through a medium is known as an electrical current.
A load increases the flow of electrical current in a series circuit. No load, no flow.
A rock that stops the flow of water would be considered an obstruction in a stream or river. This obstruction can cause water to pool or divert around the rock, changing the flow pattern. In some cases, it may lead to the formation of a small waterfall or rapids.
