There is 50 mA of current through a coil with 250 turns. The flux is 150 µWb. What is the mmf? What is the reluctance of the circuit?     A. Fm = 1.25 At   -   R=4.3x10-3 At/Wb   B. Fm = 2.25 At   -   R=8.3x10-3 At/Wb   C. Fm = 1.25 At   -   R=8.3x10-3 At/Wb   D. Fm = 1.25 At   -   R=8.3x10-2 At/Wb

A non polarized capacitor is connected in DC circuit. Is there a danger of damaging the capacitor when the power turned on?
