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).
A silicon controlled rectifier or semiconductor-controlled rectifier is a four-layer solid-state current-controlling device. The principle of four layer p-n-p-n switching was developed by Moll, Tanenbuam, Goldey and Holonyak of Bell Laboratories in 1956.
