Figure 1: Gear Tooth Vernier Caliper.
The gear tooth thickness measuring vernier is as shown in Fig. 1. It measures the thickness of the tooth on pitch circle i.e. chordal thickness.
For the transistor to act as an amplifier is must be operated in its active region. The method of applying external voltages to operate the transistor in the active region is known as Transistor Biasing. For achieving a perfect amplification in amplifier circuit proper biasing is needed.

The configuration in which emitter is common to both sides of configuration is known as common emitter configuration.
Figure 1: Common Base (CB) Configuration.
The configuration in which base is common to both the input and output sides is known as ‘common base configuration’.
