STANDARD Physics Kirchhoff's Laws MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Figure shows currents in a part of an electric circuit, then current I is
A
1.7 A
B
2.0 A
C
1.3 A
D
1.0 A
Correct Answer
Option A
Detailed Explanation
Applying Kirchhoff's first law, the sum of currents entering a junction equals the sum of currents leaving. Therefore, I = 2 + 2 - 1 - 1.3 = 1.7 A.
