Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifier?
Yes1
How does a transistor function as an amplifier?
A: The small base current will control the collector current flow by adding a resistor this changes of current flow will be evident as a voltage amplifier.
When a transistor is used as an amplifier increasing the base current will cause an increase in?
Increasing base current causes a proportionate increase in collector current - proportionate to hFe, unless the transistor is operated outside of linear mode.
What is the use of transistor in water level indicator?
It is used to amplify the current. The common-emiiter amplifier is designed so that a small change in voltage (Vin) changes the small current through the base of the transistor; the transistor's current amplification combined with the properties of the circuit mean that small swings in Vin produce large changes in Vout. Various configurations of single transistor amplifier are possible, with some providing current gain, some voltage gain, and some both.
Why base in grounded in common emitter transistor as amplifier?

Difference between cascode and cascade amplifier?
cascade: the output of one amplifier stage is connected to the input of another amplifier stages, it's also connected in series. cascode: it said to be cascode, when it has one transistor on the top of another where a common emitter transistor drives a common base transistor.
What if base current is zero in a transistor used as an amplifier with common emitter configuration?
output current is zero
How does the input resistance of the transistor in the common base amplifier compared to that of a common emitter?
Much lower. Check out electronics sites to get the formulae for each.
Why transistor burns?
If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
What is base with modulation?
AM wave is produced by applying the modulating voltage to the base of a transistor amplifier.
What is the explanation for the working CE BJT amplifier?
In electronics, a common-emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies, typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input, the collector is the output, and the emitter is common to both (for example, it may be tied to ground reference or a power supply rail), hence its name.
How should the two transistor junctions be biased for proper transistor amplifier operation?
Emitter-Base junction should be forward biased.Collector-Base junction should be reverse biased.
How work amplifier?
amplifier consists of active components like transistor fet etc,. for example transistor, it produces high output is common emitter configuration. when u give weak signal to the base of the transistor and the output is taken in collector terminal(amplitude of the weak is increased, so the output is high ) its known as amplifier

What can the input of a transistor be called?
The input of a transistor is typically referred to as the "gate" in a field-effect transistor (FET) or the "base" in a bipolar junction transistor (BJT). In both cases, the input controls the flow of current through the transistor, allowing it to function as a switch or amplifier in electronic circuits. The gate or base receives the input signal that modulates the transistor's operation.
