Question: A capacitor in an LC oscillator has a maximum potential difference of 17 V and a maximum energy of 160μJ . When the capacitor has a potential difference of 5V and an energy of 10μJ, what is the energy stored in the magnetic field?

Options:

A) 10μJ

B) 150μJ

C) 160μJ

D) 170μJ

Show Answer

Answer:

Correct Answer: B

Solution:

  • Ue+Um=160Um=160Ue=16010
