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).
Diodes: A Diode is an electronic device that allows current to flow in one direction only. It is a a semiconductor that consists of a p-n junction. They are used most commonly to convert AC to DC, because they pass the positive part of the wave, and block the negative part of the AC signal, or, if they are reversed, they pass only the negative part and not the positive part.
