Question

Which of the following statement is not correct about two parallel conductors carrying equal currents in the same direction?

• A. each of the conductors will experience a force
• B. the two conductors will repel each other
• C. there are concentric lines of force around each conductor
• D. each of the conductors will move if not prevented from doing so

Answer 1

The correct option is B the two conductors will repel each other

When two conductors carrying equal current both the conductor experiences a force which is perpendicular to the wire and are equal. Since both these forces are equal and towards each other, both the current carrying wire will be repelling each other.
