Five conductors are meeting at a point x as shown in the figure. What is the value of current in fifth conductor?

  1. 3 A away from x    
  2. 1 A away from x    
  3. 4 A away from x    
  4. 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
