6.9 Mutual inductance of a pair of coils, $μ$ = 1.5 H

Initial current, $I_{1}$ = 0 A

Final current, $I_{2}$ = 20 A

Change in current, dI = $I_{2}$ - $I_{1}$ = 20 A

Time taken for change, dt = 0.5 s

From the relation of induced emf e = $\frac{d \emptyset}{d t}$ , where $d \emptyset$ is the change in the flux linkage with the coil ……………(1)

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.
