Question

106) Que. 2.: Answer the following: 2) For a transistor le - 15 mA, la = 0.5 mA. Find the value of current amplification factor. ​

Answer 1

Answer:

Explanation:

Given: We have given the value of collector current = 15mA = 15×A

We have also given the value of base current = 0.5mA = 0.5×A

To Find: Here we have two find the current amplification factor

Solution:

We know the formula of current amplificator factor

here,

is the collector current,

is the emiiter current,

is the base current,

Here, we have to find the emitter current, beacuse for current amplification factor we need the value of emitter current.

We have the relation for base current, emitter current and the collector current,

Now, we put the value of collector current and the base current.

× + ×

×A

Now, we have the value of emitter current.

Now, we easily find the current amplificaation factor.  

So, the current amplification factor is
