a capacitor is charged up to 6V , then disconnected from the power supply and connected in series with a 0.2mh inductor. the period of oscillation of the circuit is then measured to be 8.3*10^-5 s
a) determine the numerical value of the capacitance
b) calculate the maximum current in the circuit
c) determine the total energy of the circuit
Find the change in internal energy using first law of thermodynamics.
