Force between Parallel Straight Current-Carrying Conductors
Class-12 Nootan ISC Physics Solution Ch-7 Moving Charges and Magnetic Field. Step by step solutions
Que-35: Calculate force per unit length acting on the wire B due to current flowing in the wire A. (ISC 2018)
Ans:
Since current in wires is flowing in same direction wire are attracted
Que-36: Two long, parallel, straight wires A and B carrying currents of 8.0 A and 5.0 A in the same direction are placed 4.0 cm apart. Estimate the force on a 10 cm section of wire A.
Ans:
Que-37: A long horizontal rigidly supported wire carries a current of 100 A. Directly above it and parallel to it is a fine wire that carries a current of 200 A and weighs 0.05 N/m. How far above the lower wire should the fine wire be kept to support it by magnetic repulsion?
Ans:
Que-38: Two very long, straight, parallel wires currents of 10 A and 20 A respectively and are at a distance 20 cm apart. If a third wire C (length 15 cm) having a current of 10 A is placed between them, how much force will act on C? The direction of current in all the three wires is same.
Ans: The force by two wire will be opposite both the wire will attract the middle wire.
Because current in B is more than A
