You aren't giving us anything to work with.

How can we possibly tell you if the answers you got are correct when you won't tell us what answers you got?

How we can tell you what you might have done wrong when you won't tell use what you did?

When doing the lab, you can always do a screenshot of your computer to upload when you have questions.

Hello,

Attached are the screenshots from my laptop using the livewire software.

That was i how i measured the VB,VC,VE and VCE in the first experiment.

Please,kindly correct my errors

 

You don't need three meters to take one reading. What is meant by Vb? Where do you connect the meter leads? That same question applies to all the mentioned measurements.

Redo your pictures using one meter. Start with just Vb.

Dear Sir,

VB is the base voltage and i got 1.10v from the measurement.

kindly check again the attached files.

thank you

 

Why did you change the value of C1?

 

Why did you change the value of C1?

sir,
i just found out the correct value of C1 in the original Manual.,

i was supposed to input 10uf...i can change the value of C1 but i want to be sure if i am getting it.

i awaits any corrections

 

the measurements are as follows after changing the values of C1 back to 10uf;

VC= 4.82V

VB= 1.10V

VE= 419.36mV

VCE= 4.40V

 

am i correct on this please?

 

Can you measure Vbe ... Your transistor model is probably not 0.7V like we "assumed" in the calculations.

Attached is a lecture about DC Analysis of BJT circuits. It might help you .

VBE is 693.20mV when measured.

thank you for the attached lecture note,i`ll go through it.....i really do appreciate

 

Dear All,

i was not able to finish this assignment and i will be submitting it tomorrow.

hoping to get any assistance.i dont want to fail

best regards
