Hi Dorke
Can you check this for me to see if I'm anywhere near
[(R2)^2 +(XL1)^2]^0.5
100^2
Z=R2*1/(Vout/Vin)
R2 x 1 =100 = 100
Vout 0.7v/Vin 1.0 v = 0.7
Z= 100/ 0.7
Z = 142.8571429
0.7= [(R2)^2 +(XL1)^2]^0.5 / [(R1+R2)^2 +(XL1)^2]^0.5
solve for XL1
[ (R2)^2 + (XL1)^2 ]^0.5 / [ (R1 +...
This setup has different resistance measurements to solve Z I need to re arrange this equation ? R2*1/(Vin/Vout)
Total resistance is 22100 ohms
resistor 22000 ohms
Inductor is 100 ohms
Hi Dorke
Thanks for pointing that out , I was wondering why the calculation wasn't matching when using this equation for Z = Square root R^2 + XL^2
I understand now that the line is crossing the horizontal axis of the phasor so the equation is slightly different and the vout is taken across...
Hi Dorke
Can you check this for me
Z=R2*1/(Vin/Vout)
R2 x 1 =1500 = 1500
Vin 1v / Vout 0.7v = 1.428571429
Z= 1050
-----------------------------------------------------------------------------------------------
(XL1)^2 =[R2*1/(Vin/Vout)]^2 - (R1+R2)^2
(XL1)^2 =[1500*1.428571429]^2 - (1610)^2...
Hi Dorke
I really appreciate all your help, can you check the equations below to see if I'm doing them correctly
Z=R2*1/(Vin/Vout)
R2 x 1 = 1.5 = 1.05 k
Vin 1v / Vout 0.7v = 1.428571429...
Hi Dorke
I see now :)
The resistor is between terminals 1 and 3 1.500 k
The inductor is on the input pin 2 and the resistor is on GND pin 1 giving us a meter reading of 1.610 k between pins 1 and 2 (inductor + resistor )
When we look at the oscilloscope readings it makes it an RL lag...
Hi Dorke
Here's another shot in the dark :)
Did you put the inductor on the horizontal branch because the first equation is to calculate XL1 by using the input and output voltage information from terminals 2 & 3
Hi Dorke & Alec
To try and calculate I have been using the same style layout that Alec provided but I'm really stuck as no figure is shown for the inductor (h) and the only way I can try and find the impedance is by using V = IZ , but when I use this equation things don't add up on the...
Hi Everyone
I need some help finding the inductance of a RL circuit
All the information I have is that the resistor in the circuit is 1.500 k ohm
input to the RL circuit is 1 volt 80 khz
output 0.7 volts 80 khz
I have no information for the inductor
Every equation I find needs either...
