Question

The CE amplifier circuit are preferred over CB amplifier circuit because they have

• A. lower amplification factor.
• B. larger amplification factor.
• C. high input resistance and low output resistance.
• D. none of these.

Answer 1

The correct option is B larger amplification factor.

CE amplifier -This transistor configuration is probably the most widely used. The circuit provides a medium input and output impedance levels. Both current and voltage gain can be described as medium, but the output is the inverse of the input, i.e. ${180}^o$ phase change. This provides a good overall performance and as such it is often thought of as the most widely used configuration or can be said as that we get a good amplification factor here in CE amplifier compared to CB amplifier.
