Question

A 7.90-nF capacitor is charged up to 14.0 V,then disconnected from the power supply and connected in series through a coil. The period of oscillation of the circuit is the measured to be 8.80*10-58 Part A Calculate the inductance of the coil. ANSWER: L= H Part B Calculate the maximum charge on the capacitor ANSWER Q с Part 6 Calculate the total energy of the circuit. ANSWER: J Part D Calculate the maximum current in the circuit ANSWER: 1 =

Answer 1

Solution frequency 27TLC Time period = 25 VIC AT C= 7.gonF, Valtage = 14:00 Time period = 8.80X10-58 Part A 25cc = 8.8410-5 VLA4, 90x100 c 21 - 808x10-58 L = 8-8410-512 25 709X10-9 10-5)? L-0-02483 H L = 24.83 mm Part B maxium change on the copaciley js B B = CV = 7.9X10-9 x 14 B = 110.6 nc
