If an inductor is connected in a circuit such that the input

If an inductor is connected in a circuit such that the input it receives is the combination of a low frequency sinusoidal signal and a direct current signal, what is the output most likely to contain? both the sinusoidal signal and the direct current signal the direct current signal the low frequency sinusoidal signal neither the sinusoidal signal nor the direct current signal none of the above: Which of the following circuits is most likely the one associated with the phasor diagram that is provided?

Solution

20) option a

21) option a because in the phasor diagram, I2 leads the I1 by 90 degrees it happens with capacitance only
