- Homework Statement
- I tried to perform an experiment in my school physics lab with an RLC circuit. I plotted the variation of voltage across resistor against frequency of source.

- Relevant Equations
- Frequency of resonance ##\omega^2 = \frac {1} {LC}##

From the graph below of voltage across resistor vs. source frequency, it can be seen that resonance is obtained at 828Hz. But, on calculating the inductance of my inductor (homemade) using ##\frac {1}{(2\pi f)^2C}##, I got 7.9mH. But this is greater than the inductance of the solenoid calculated using ##L=\mu n^2 Al##, where ##\mu## is permeability of vacuum, A is the cross-section of solenoid, l is the length of solenoid and n is the number of turns per unit length . Could someone please help me understand why. Please be kind to help.

The capacitor i used was rate ##4.7 \micro farad##.
