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).
Collector-emitter: The main current that flows through the transistor. Voltage placed across the collector and emitter is often referred to as V ce, and current flowing through the collector-emitter path is called I ce. Base-emitter: The current path that controls the flow of current through the collector-emitter path.n a PNP transistor, the emitter is the positive side of the transistor. The collector and base are the negative sides. Most circuits that you can build with an NPN transistor can also be built with a PNP transistor. But if you do, you must remember to flip the power connections.
