Question

jhonny got a task from his teacher to make a high pass filter using a 160 mH inductor and 3300 like shown above, when jhonny use sinus wave 5 Vpp and he use 27 kH the output value is 880 mV, and with the same resistor and inductor but with different frequency 57 kHz ge got 480 mV

Jhonny ask his teacher why this happened and the teacher said it happened because there is a parasitic capacitance in his inductor ,so the teacher give jhonny this graph

and it look exactly like what jhonny data is, and the circuit look like this

explain why this happened using voltage divider how the xc affect the vout ( the target is still voltage in the inductor )

R1 し1 OUTPUT INPUT -80 3 5-110 140 -170 11び 1-10 1 10 TRTOLTNCY () 1-10 1-1 1-10 1.10 Input Output is actually as shown below: Cparasitic Rcoil

Answer 1

-- Amped ance is S C 小o-C So crt will loor ie ル11 So CA ll look ike
