Blow your nose. Before using the nasal spray, you need to clear your nasal passages. Otherwise, the medication might get caught in the front of the nostril, where it will be less effective. Blow your nose until you have completely cleared your nostrils. 1  Do not blow your nose after using the spray.
The basic difference is the pin of the transistor that is grounded. The common collector has the collector pin grounded, common emitter has the emitter pin grounded and common base, as you guessed it, has the base pin grounded. The following article explains the differencnes perfectly.
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.
