The emitter-base junction is forward biased and
the collector-base junction is reverse biased
A common emitter amplifier has a higher
current gain than a common base amplifier
A common emitter amplifier has a higher
voltage gain than a common base amplifier
All the above statements are ture​

Answer 1

Answer:

and then you should receive any other way of saying they do I

Answer 2

Concept

By increasing the power of a weak signal, a transistor functions as an amplifier. The emitter base junction is kept in a forward biassed condition by the DC bias voltage that is provided to it. No matter how the signal is polarised, this forward bias remains.

Explanation

• When configured as a common-emitter (CE) transistor, it functions as an amplifier.
• Base-emitter junction is forward biassed while collector-base junction is reverse biassed in this setup.
• The input signals allow the emitter current to flow when the transistor is biassed to be used as an amplifier, which subsequently helps to drive the collector current.
• When this current passes through the load resistor, a significant voltage drop occurs across.
• This demonstrates the amplifier function of a transistor.

Hence statement The emitter-base junction is forward biased and the collector-base junction is reverse biased is true about a transistor amplifier
