AP EAMCET · PHYSICS · Current Electricity
Current through the branch \(B D\), in the given circuit is
- A \(6.6 \mathrm{~A}\)
- B \(5.0 \mathrm{~A}\)
- C \(4.3 \mathrm{~A}\)
- D \(3.2 \mathrm{~A}\)
Answer & Solution
Correct Answer
(B) \(5.0 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
Let \(i_1\) and \(i_2\) be current drawn from battery 15 \(\mathrm{V}\) and \(30 \mathrm{~V}\), respectively as shown below Hence, by KCL, Net current passing through branch \(B D\) \(i_3=i_1+i_2\) ...(i) By KVL, in loop \(A B D A\), \(15-6 i_1-3\left(i_1+i_2\right)=0\)…
