How can I get value of R L C when they are connected in series in a box.And we are given CRO & function gentor

AN R L C is given in a box and we are to determine value of these R L C .how can I do it using a CRO and function generator.we are allowed to change input patterns with function generator

Using your Oscilloscope and function generator.


Start by using a standard sine wave in and measure the output.


Change the frequency.


Change to a Square wave and again change the frequency. Try a long duty cycle which is almost equal to a DC input, what is the signal output. This will determine the RC time constant.


Then you use the Frequency relationship to determine L. Where impedance Z = 2pf * L and for C: Z = 1/(2pfC)


Where p = pi= 3.14 and f = frequency.


You Also know that Zeq (Z equilvalent for L %26amp; C) + R at resonant frequency gives the highest Current I.
