Chapter 4: Q30E (page 949)

Two long, parallel wires are separated by a distance of 2.50 cm. The force per unit length that each wire exerts on the other is4.00x10-5 N/m , and the wires repel each other. The current in one wire is 0.600 A. Are the two currents in the same direction or in opposite directions?

Short Answer

Expert verified

The current flowing in both wires are in opposite direction.

Step by step solution

01

Attraction and repulsion between two parallel current carrying wires

When the current is flowing in same direction in both parallel wires then attraction occurs between two wires.

When the current is flowing in opposite direction in both parallel wires then repulsion occurs between two wires.

02

 The direction of current flow in two wires

Since, both wires repel each other.

Therefore ,current must be flowing in opposite direction in wires
