Question

The four wires from a larger circuit intersect at junction A as shown. What is the magnitude and direction of the current between points A and B?(a) 2A from A to B(b) 2A from B to A(c) 3A from A to B(d) 2A from B to A

Answer 1

hi you need to use the kitchoff first law which is the current which is flowing to the point A you need to consider the current positive and the current which is flowing opposite direction of a you need to consider that current negative show the magnitude will be 3 ampere a to b
