hello
I have this circuit
this is the question
4. Consider the circuit below:-
L1, R1 and C1 are your original 3 components. C2 and R2 are additional components that you will be given (they will be known values).
The final report should be written up in chronological order with details of activities and analysis at each stage. Theoretical and practical values should be compared and variations should be investigated and corrected or justified. Photographic evidence can be used at any stage if considered appropriate
I have simulated the circuit to try and get some idea of what currents to expect. I then made the circuit and measured the current. for the above example I got 44mA instead of the uA reading in the picture above. that leads me to believe I am doing something seriously wrong. I have had problems with measuring values and getting the correct values. the inductor is a transformer, a large chunky thing. would it work better with an axial inductor? I measured the capacitors with a meter and got the correct value along with the resistors. they were within tolerance. but I cant understand what im doing wrong.
I have just tried a different meter in multisim and got 1A reading instead
so yeah.....what the hell!?!
any help would be great!!!
I hope you all had a merry Christmas and happy new year!!!!
guess what Christmas soon! only another 300 (odd) days to go!!!
thanks
simon

- Connect the circuit to a 500 Hz supply at any suitable voltage and measure the branch currents and
- the supply current.
- Using complex notation verify these values.
The final report should be written up in chronological order with details of activities and analysis at each stage. Theoretical and practical values should be compared and variations should be investigated and corrected or justified. Photographic evidence can be used at any stage if considered appropriate
