    Correct Option - 3


    Detailed Solution:

    Z = R 2 + ( X L − X C ) 2

    Z = ( 1 2 0 ) 2 + ( 1 0 − 1 0 0 ) 2 = 1 5 0 Ω

    ω = 1 L C = 1 1 0 − 1 × 1 0 − 4 = 1 0 5

    ? ω = 2 π f

    ⇒ f = 1 0 3 2 π 1 0 = 5 0 H z

X C = 1 ω C

On increasing ω  XC decreases so Z decreases, current in circuit increases.

E = V R 2 + ( V L − V C ) 2

E = ( 6 0 ) 2 + ( 1 0 0 − 2 0 ) 2

E = 100V

Figure shows a circuit that contains four identical resistors with resistance R = 2 . 0 Ω ,  two identical inductors with inductance L = 2.0mH and an ideal battery with emf E = 9V. The current ‘i’ just after switch ‘S’ is closed will be:

R = 2 Ω

L = 2 mH

E = 9V

i = ε 2 R = 9 v 4 Ω = 2 . 2 5 A

Just after the switch ‘S’ is closed, the inductor acts as open circuit.
