Question
Five conductors are meeting at a point x as shown in the figure. What is the value of current in fifth conductor?
- 3 A away from x
- 1 A away from x
- 4 A away from x
- 1 A towards x
The correct answer is: 1 A away from x
According to Kirchhoff’s first law
(5A)+(4A)+(-3A)+(-5A)+I=0
Or I=-1A
