Correct Option - 4

Detailed Solution:

Given, I = 5 sin (120πt), $ω$ = 120

$T = \frac{2 π}{ω}$

$T = \frac{2 π}{120 π} = \frac{1}{60} s e c, \frac{T}{4} = \frac{1}{60 \times 4} = \frac{1}{240} s e c$

The value of alternating emf (E) in the given circuit will be

Vishal Baghel

$E = \sqrt[]{V_{R}^{2} + {(V_{L} - V_{C})}^{2}}$

$E = \sqrt[]{{(60)}^{2} + {(100 - 20)}^{2}}$

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:

Vishal Baghel

R = $2 Ω$

L = 2 mH

E = 9V

$i = \frac{ε}{2 R} = \frac{9 v}{4 Ω} = 2.25 A$

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