Question

Problem 10

Answer 1

Given information

Given:

two insulated electric wires carrying AC are placed close together;

To determine the advantage in placing them together.

Step-by-step explanation

Step 1.

According to the laws of electromagnetism, a wire carrying AC current produces a magnetic field around it. By placing the two wires close together, the magnetic field created by the changing current moving one way in one wire is approximately cancelled out by the magnetic field created by the current moving in the opposite direction in the second wire.
