Kirchhoff's Laws & Measuring Instruments

The figure shows currents in a part of electric circuit. Then current I is

Show answer and solution

Answer: (a)

First junction: $1 + 4 = 5\text{ A}$ flows on.
Second junction: $0.5\text{ A}$ leaves, so $5 - 0.5 = 4.5\text{ A}$ flows on.
Third junction: $1\text{ A}$ leaves, so $I = 4.5 - 1 = 3.5\text{ A}$ .
So the answer is (a) 3.5 A.
