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.

What is current amplification of a transistor?
a transistor ampify the current i.e. you the output current proportional to the input one. in CE amplifier , this ratio is more than one Ic/Ib = current amplification factor this extra ampitude comes from the biasing batteries used.
What is the amplification capacity of a typical transistor?
typically the amplification of a transistor 100 times.
What did a transistor do?
amplification
Which of the transistor configuration is prefer?
It depends on what you want to do with the transistor. Class A, common emitter, is used for voltage amplification. Class C, common collector, is used for current amplification. There are other classes and configurations but, again, it depends on what you want to do.
What is hfe and hfc in transistor?
I don't know about hfc, but hFE is the amplification factor by which the transistor amplifies the base current. Therefore, if hFE is 100, the base current is amplified by a factor of 100.
What is the typical use of a transistor in an analog circuit?
amplification
Can you do amplification without transistor and is it possible to design oscillator using diode?
Magnetic amplifiers and vacuum tubes don't need transistors to amplificate electricity current. You can get a transistor by two oppositely connected diodes.
What is meant by transistor AD162?
An AS162 transistor is a type of PNP transistor commonly made of germanium. This is an older kind of transistor that was often found in power amplification circuits.
What is application of transistor?
Application: 1.For amplification of sound. 2.logic switch 3 oscillation 4 power amplification.
What is transition frequency of a transistor?
The transition frequency of a transistor is the frequency in which the transistor will no longer provide any amplification or gain output. The frequency is out of the transistors's range.
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.
How does a transistor make a signal bigger?
by injecting a small current into the base a larger proportional current will flow in the collector by adding a resistor into the path a big voltage drop will be evident therefore voltage amplification
