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.
Why ce configuration of transistor has a 180 phrase difference in output?
A: As current begins to flow the action on a resistance will be a voltage drop which is inversely proportional to the current. Making it a voltage amplifier as opposed to a tube where it is a current amplifier
Why does a CE amplifier have a high gain?
GAIN is a function of load current but basically a small current in the base will make a big change of collector current therefore making a transistor a voltage amplifier as opposed to a current amplifier
Main use of a Common base transistor amplifier is?

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.

When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
Why mostly a transister is used as amplifier than diode?
A diode is not an amplifier. It is a rectifier with asymmetrical voltage breakdown voltages. Usually the forward voltage is around 0.6V to 0.7V (silicon), and the reverse voltage is smaller than breakdown voltage, which is much higher. A transistor can be used as an amplifier, by taking into account the fact that the voltage breakdown curves vary, usually collector-emitter, as a function of some other current, usually base-emitter, but this depends on the class of the amplifier and whether or not the transistor is driven into saturation.
How current amplification is occur in a transistor?
A: Vacuum tubes are current amplifiers transistors are voltage amplifier. The voltage drop across the collector resistor causes amplification since very little current in the base will change a large current in the collector.
Main use of a Common collector transistor amplifier is?
No voltage gain
In a well-designed circuit the transistor will act like what?
Voltage amplifier
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
