274631 With increase in frequency of an A.C. supply, the inductive reactance

1 decreases
2 increases directly with frequency
3 increases as square of frequency
4 decreases inversely with frequency

AC (NCERT)

274632 An alternating $\text{emfE}=440\text{sin}100\pi \text{t}$ is applied to a circuit containing an inductance of $\frac{\sqrt{2}}{\pi }$.H. If an a.c. ammeter is connected in the circuit, its reading will be :

1 $4.4\text{A}$
2 $1.55\text{A}$
3 $2.2\text{A}$
4 $3.11\text{A}$
