AC Bridge Problem

I'll bet your professor would not like your posting your home work problem here. You are supposed to dig this out yourself. Get with your fellow students and work it out.

i am not a student. i completed my graduation 5 years before and working in a power sector. The problem was given by my friend and he wants to get it resolved ,since i forgot the equations , i couldnt resolve it.otherwise it may not have come in this posting.......

Well remind your friend that they should define the transfer function in the La Place domain. To do this one assumes that the diode current paths are ideal diodes with no forward dropping voltage and no reverse leakage current. Next choose a nodal or mesh analysis approach for each forward bias circuit to identify the transfer response. Next replace s with jω and solve. (Remember j=√-1 and ω=2πf) If this is not enough information to start, then open the textbook. If you don't understand what the textbook says, then ask us a specific question other than solving the problem for you. If you cannot think of a question to ask other than how do you solve this, both of you should go back to your school for a refund.

Thanks for your advice. Better read some measuring instruments book.The problem is related to that.It is a problem related to schering bridge.you substitute the values to the equation , you will the answer,now i think u shud think about going back to school for studying all these things.

The idea of homework is to get the student to think on his own. He'll not have CR4 to help in the examination!

thanks

thank you very much. It is a schering bridge used for the measurement of tan delta

hi dear, thank you very much

the bridge is " the wien bridge " not "scheringbridge "

the difference C₂ " scheringbridge "

and

R " wien bridge "
