A 15 ?F capacitor is charged to 15 V and is then connected across a 20 mH inductor.(a) How much energy is stored in the system? (b) What is the frequency of oscillation of the circuit? (c) What is the maximum current in the circuit?
a) Eng.5 C V^21.688E-3 J b) f1/sqrt(2 pi L C)728 Hz c) the peak energy in the inductor will be 1.688E-3. Isqrt(2 Eng/L)-.411 amps.
In real life this does not paintings, do no longer connect electrolytic caps in series. The leakage resistance of each and every means that the voltage heavily isn't divided as you will possibly calculate yet somewhat via the (unknown) leakage resistances. the finished C is a million/C a million/20 + a million/10 + a million/15 C 4.sixty one ?F Q CV 461 ?C comparable value is on each and each. V Q/C 461 ?C / 10 ?F 40 six.a million volts
