Question

Which current will produce electric field
AC or DC??

Answer 1

hey frnd......
For the same value of current flowing through a purely resistive wire, the magnetic fields produced by AC or DC will be the same.

If there's a capacitor or an inductor in the circuit, magnetic fields will be stronger for AC. In a purely capacitive circuit, DC won't create a magnetic field at all. (No current will flow because CRCR = ∞)

The difference between the fields produced by an AC or a DC is that the magnetic fields produced by an alternating current is a changing magnetic field (Its direction and magnitude changes with time), while for a DC the field is constant both in magnitude and direction.

Also, electromagnetic induction is possible only with a changing magnetic field, so with a DC, EMI makes no sense.

If induction in your question means ELECTROMAGNETIC INDUCTION, only an alternating current can cause EMI, and DC makes no sense.

EMI is very frequently used with AC, such as in the case of a transformer.

HOPE THIS HELP YOU ☺☺❤❤❤✌

Answer 2

In direct current (DC), the electric charge (current) only flow in one direction. Electric charge in alternative current (AC) ,on the other hand change direction periodically. The voltage in AC circuit also periodically reverses because the current charges direction.

I hope my answer you
otherwise sorry
