As peribronchial cuffing is a sign rather than a symptom or condition, there is no specific treatment except to treat the underlying cause.
Explain how a potential divider circuit can be used to produce a variable p.d. A potential divider is a circuit with at least two components (Câ, Câ)connected in series, with the output voltage taken across one of the components (Câ).
This continuous movement of free electrons through the conductors of a circuit is called a current, and it is often referred to in terms of flow, just like the flow of a liquid through a hollow pipe. The force motivating electrons to flow in a circuit is called voltage.
