What role does the capacitor play in a common$-$emitter amplifier circuit with AC coupling? Increases the power consumption $$ Provides DC biasing to the transistor Decreases the gain of the amplifier Blocks DC while allowing AC signals to pass Which parameter primarily influences the small$-$signal voltage gain in a common$-$base amplifier? $$ gm RE What is the effect of increasing RE in a common$-$emitter amplifier on the linearity of the amplifier? Increases linearity Reduces voltage gain but has no effect on linearity Decreases linearity Increases power consumption Which of the following describes the relationship between the voltage gain and the load resistance RL in a common$-$emitter amplifier? The gain decreases with higher RL The gain is independent of RL The gain increases with higher RL The gain is inversely proportional to RL
