Response:

Given data:

and

(a)

From the diagram voltage across resistor

By applying KVL at base to emitter loop we can get

We know that

(b)

Given

We can write the following KVL equation at the collectro loop

(c)

Once the transistor is in saturation

Now we can write

Now we can write the following KVL equation at base to emitter loop

By using potential divider rule we can write

Assume

Then

I hope this helps you..............
