1. The problem statement, all variables and given/known data
an experiment to determine the inductance and internal resitance of an inductor in a series LCR circuit.
I am proved with an a.c. power supply, an inductor, a capacitor substitution box, a resistor and an a.c. voltmeter
2. Relevant equations
how can i find the resonace frequency, inductance and the internal resistance of the inductor?
3. The attempt at a solution
I was suggested to use graphical method to find out the resonance frequency
but i don't know how can i do it.
