According to Kirchhoff's first law At junction A, iA B=2+2=4 A At junction B, iA B=iB C-1=3 A <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/7859fb71eafc27ddd89af94d1721d31d-.png" /> At junction C, i=iB C-1.3=3-1.3=1.7 A

Q. The figure below shows currents in a part of electric circuit. The current $i$ is

1.7 A

3.7 A

1.3 A

1 A

According to Kirchhoff's first law
At junction $A, i_{A B} = 2 + 2 = 4 A$
At junction $B, i_{A B} = i_{BC} - 1 = 3 A$

At junction $C, i = i_{BC} - 1.3 = 3 - 1.3 = 1.7 A$

Q. The figure below shows currents in a part of electric circuit. The current i is

1.7 A

3.7 A

1.3 A

1 A

According to Kirchhoff's first law At junction A,iAB​=2+2=4A At junction B,iAB​=iBC​−1=3A At junction C,i=iBC​−1.3=3−1.3=1.7A

Q. The figure below shows currents in a part of electric circuit. The current $i$ is

According to Kirchhoff's first law
At junction $A, i_{A B} = 2 + 2 = 4 A$
At junction $B, i_{A B} = i_{BC} - 1 = 3 A$

At junction $C, i = i_{BC} - 1.3 = 3 - 1.3 = 1.7 A$
