COMEDK · Physics · 19. Current Electricity
The magnitude of \(I\) in ampere unit is
- A \(0.1\)
- B \(0.3\)
- C \(0.6\)
- D None of these
Answer & Solution
Correct Answer
(A) \(0.1\)
Step-by-step Solution
Detailed explanation
Consider the diagram with current distribution as shown below. As voltage is same in parallel combination, so \(\begin{aligned} &60 I=(15+5) I_{1} \\ &60 I=20 I_{1} \text { or } I_{1}=3 I...(i) \end{aligned}\) Similarly, \((15+5) I_{1}=10\left(1-I-I_{1}\right)\)…
