A; Is not a current multiplier it is merely an empirical number assign to a part to indicate its capability at a certain current. The value can vary from 10 to 200 for the same transistor depends on the current that is is suppose to carry.

How do you calculate the current gain of a transistor?
Bipolar transistor current gain is also called "Beta," or the h-parameter "hfe." beta = current_out / current_in The beta of a BJT is mostly determined by the thickness of the Base region, and by the excess doping in the Emitter relative to the Base. A thin Base and a heavily-doped Emitter leads to a high value for current gain. In a BJT, beta = Ic / Ib In a FET, beta is usually taken as infinity, since no current flows in or out of the gate. Beta is an impirical number. It means nothing unless the Ic is known or the load. It can have a beta from 1000 to 10 it all depends on the load.
How do you get stud multiplier x10 in lego star wars 3 beta?
you have to get the red brick that unlocks it. in the Harry Potter Lego game you have to buy the upgrade but im not sure if its the same in Lego star wars
What is the alpha beta teta of a bipolar junction transistor?
alpha is the common base current gain = Ic/Ie.beta is the common emitter current gain = Ic/Ib.
Why gain increases in low frequency region in BJT?
Because Beta (current gain) in a transistor is inversely proportional to frequency. Hence it increases as frequency decreases. Also the ac voltage gain is directly proportional to Beta.
Where you can get free Tamil fonts download?
analog multiplier
Variation in beta DC to collector current?
variation in beta dc with collector current
Why common collector amplifier current gain is equal to beta?
Actually the current gain is equal to Beta+1, not Beta. The current from/into the emitter is the sum of the current into/from the collector and base. Of course this assumes linear operation.For a proof: Ie + Ib + Ic = 0Ic = Beta * IbIe + Ib + Beta * Ib = 0Ie + (Beta + 1) * Ib = 0Ie = -(Beta + 1) * Ib
What are the advantages of darlington pair?
A darling ton is a beta current multiplier. it output can be used to drive low impedance device
How do i Calculate base current from collector current and resistance?
Ib =Ic /beta beta is the gain factor of the amp.
Which configuration amongst CCCECB gives no current gain?
CB gives a current gain of beta/(beta+1), which with typical beta values is just under one. Note that this current gain value is also known as alpha.
Beta calculation of icici bank?
current beta i.e. on Aug. 2009 for the ICICI bank is 1.56
How does beta factor affects the transistor?
Beta is current gain of that transistor,whatever be the input the trasistor. we will get the output multiplied by the beta. for example in CE amplifer if Base current is 10 microampere and beta of that transistor is 100 then collector current would be 1mA i.e. 100 times greater than input current

How you differentiate base bias and emitter bias?
On the emitter there is base current which is basically a function of Beta and only at that particular current. Unfortunately the beta factor is a non linear function and it is strictly related to collector current
Types of multiplier?
tree multiplier CSA (carry select adder) multiplier shift & add multiplier Higher radix multiplier
Is a seesaw a force multiplier or a speed multiplier?
force multiplier
What is the maxium current gain of common base amplifier?
If Beta is infinite, then the current gain will be unity.
