Question

class 12 physics
with explanation please​

Answer 1

Answer:

5 A

Explanation:

Apply kirchoff law which states that the current entering=current leaving. 3 and 4 A ampere are entering 2 A is leaving so equalise them we get 5 A in AB branch.

Answer 2

Answer:

5A

Explanation:

Apply junction(kirchoff's) law

that is

current coming into the junction = current going out of the junction

let us assume current going out of junction in AB wire

3+4=i ( in AB ) +2

current in wire AB =+5

Current is positive so that we have assumed correct

That is current going out of the junction
