A) 4.5 A
B) 6.0 A
C) 3.0 A
D) Zero
Correct Answer: A
Solution :
Let V be the potential of the junction as shown in figure. Applying junction law, we have or \[\frac{20-V}{2}+\frac{5-V}{4}=\frac{V-0}{2}\] or 40 ? 2V + 5 ? V = 2V or 5V = 45 Þ V = 9V \ \[{{i}_{3}}=\frac{V}{2}=4.5A\]You need to login to perform this action.
