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.
Base (chemistry) A base is a substance that can accept a hydrogen ion (H+) from another substance. A chemical can accept a proton if it has a negative charge, or if the molecule has an electronegative atom like oxygen, nitrogen, or chlorine that is rich in electrons. Like acids, some bases are strong and others are weak. The weak bases are less likely to accept protons, while the strong bases quickly take protons in solution or from other molecules. An acid is a base's chemical opposite. An acid is a substance that will donate a hydrogen atom to the base. Bases have a pH greater than 7.0. Weak bases generally have a pH value of 7â9 while strong bases have a pH value of 9â14.
