<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-hqqzobze38ecervl.jpg" /> I1 + I2 = 2.1 A &hellip;.(1) 18 I1 = 24 I2 &hellip;(2) ⇒ 3 I1 = 4 I2 = 4 (. 2.1 - I1 .) I1 = (8.4/7) = 1.2 A

Q. In the following network, the current flowing through $15 Ω$ resistance is

$0.8 A$

$1.0 A$

$1.2 A$

$1.4 A$

$I_{1} + I_{2} = 2.1 A$ ….(1)
$18 I_{1} = 24 I_{2}$ …(2)
$\Rightarrow$ $3 I_{1} = 4 I_{2} = 4 (2.1 - I_{1})$
$I_{1} = \frac{8.4}{7} = 1.2 A$

Q. In the following network, the current flowing through 15Ω resistance is

0.8A

1.0A

1.2A

1.4A
