Small is relative term, current gain of the transistor decides how small base current would be than collector current. Most of the emitter current of electrons diffuses through the thin base into the collector. Moreover, modulating the small base current produces a larger change in collector current.Small is relative term, current gain of the transistor decides how small base current would be than collector current.

What else can I help you with?
Why the base current is responsible to turn on or off a transistor?
base current is very small and we should apply ainput on base current
Why the base current in the transistor is so much less than the collector?
as the base current is very small compared to the emitter current,the collector current is nearly equal to the emitter current..

Why is the base current in transistor very small?
Because a transistor's collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch. A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.
Why is the base lightly doped in a tranistor?
Since the base in an n-p-n transistor is kept very thin, very few electrons get to recombine with holes and escape out of base, most of the electrons are injected from emitter into the collector. As a result, Base-current is very small. Whereas the Collector-current is almost equal to the Emitter-current.
When is the current flowing in a circuit said to be very small?
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
Why is the base of transistor made very thin?
Base of transistor is made thin just to get Collector current equal to Emitter current.
What is the difference between common base emitter transistor and common base transistor?
Common base transistor if the emitter is open current Ie=0 but a small collector current thus exist.this current is reversed biased collector to the base voltage it is represented by Icbo while common emitter is d base terminal is open circuit and the base junction is reversed biased current Icbo flow from the tcollector to the emitter in the external circuit this current is called leakage current.
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 no load current is 5 percent of full load current in motor?
As the no load current is the current due to core losses of the motor which is very small .in no load terminals are open circuited no current flows through it, a small current flows which is due to core
Does a transistor allows control of large currents with small current signals?
Yes. The ratio of collector current and base current is DC gain, also known as beta, or hFe.
When measuring a large current flow should you use a shunt with zero resistance?
It is not a shunt with zero resistance. It is very small, but it is not zero. The large current develops a small voltage across the small resistance. Measuring that small voltage gives you a proportional measurement of the current.
