two parallel conductors are carrying the current in the same direction.which of the following statements is true? (a)there is arepelling force between the conductors (b)the force increases when the distance between the conductors is increased (c)there is an attaracting force between the conductors (d)the force increases when the distance between the conductors is decreased
1 3810In the solution of load flow eqation, Newton raphson method is superior to the gauss siedal method because (a)the time taken to perform one iteration in the NR method is less when compared to GS method (b)the number of iterations required in the NR method is more compared to that in the GS method (c)the number of iterations required is dependant on the size of the system in the NR method (d)convergence characteristics of the NR mehod are not affected by the selection of the slack bus
