Hi , good to see a physics problem. Kirchhoffs law states the conservation of currents inside a circuit. That is current flowing into a point is equal to current flowing out a point. To answer the question. Current at point (a) comes from two 3A current, summing a 6A current. Current at point (b) is divided into a 3A current and a 1A current, implying it is a 4A current. Point (c) is similar to the situation of point (a). It combines a 2A current and a 8A current, resulting a 10A current. The part involving point (b)(c)(d) : Current flows through point (c) is divided into path passing point (b) and another path passing point (d). Therefore we should have the relation c = b + d. So point (d) has current 6A. Current at (d) is divided into two currents , one is 4A and the other is (e). So (e) is 2A. Remarks. You may imagine currents as water and circuit path as river. When two rivers / circuit path emerge , their flow of water / current add together. When river diverges , their baby rivers must in total equal to the amount of mother river.

I wrote in separate paragraph but somehow the app combine them. So it looks messy.

Firstly, your question posted should be in English. Secondly, it looks more likely to be Chemistry than Mathematics. Consider using other platforms for such question.
