From KCL we have <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/457b2cfbc5d59036747ddf18b20b00bd-.png" /> i =(72/8 × 103)=9 × 10-3 A i × 6 =(9-i) × 3 i =3 mA

Q. What current will flow through the $2 k Ω$ resistor in the circuit shown in the figure?

3 mA

6 mA

12 mA

36 mA

From KCL we have

$i = \frac{72}{8 \times 1 0 ^{3}} = 9 \times 1 0^{- 3} A$
$i \times 6 = (9 - i) \times 3$
$i = 3 m A$
