Question

The value of current i in the following network of wires is 4A 1A 2A 3A​

Answer 1

Answer:

3A

Explanation:

see 4A + 1 A is entering = 5 A

so 5 A should go out .

therefore already 2 a is leaving as per the diagram .

so 5A - 2A = 3A

which is probably the answer

Answer 2

Given :   A figure showing current entering and leaving at a node

To Find : Value of  current i

Solution:

Kirchhoff's Current Law (KCL)

Total current entering a circuits junction is exactly equal to the total current leaving the same junction.

4A  and  1 A  are entering to Node

and 2A  and i  are leaving the node

=> i  + 2  =  4 +  1

=> i  = 3 A

Hence Value of i is 3A
