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.
Best Answer: The 'h' (lower-case) stands for 'hybrid model'. Transistor amplifiers may be modeled as 2-port devices with 1 port being the 'input' and the other port the 'output'. Any 'black box' 2-port device has sets of parameters that can be used to describe the electrical characteristics of what's inside the box. One type of these parameters is called the hybrid set, or h parameters. For the common-emitter bi-polar junction transistor amplifier h21 is called hfe. 'h' is for hybrid, 'f' is for 'orward, 'e' is for common Emitter. The difference between hFE and hfe is: FE is for a fixed DC bias and a fixed DC current gain (and that must be specified for each value of hFE).
