A Wire Carries an Alternating Current I = I0 Sin ωT. is There an Electric Field in the Vicinity of the Wire? - Physics

Advertisements
Short Note

A wire carries an alternating current i = i0 sin ωt. Is there an electric field in the vicinity of the wire?

Advertisements

Solution

When an alternating current passes through a conductor, the changing magnetic field create a changing electric field outside it. An electromagnetic field is radiated from the surface of the conductor. There is a time-varying electric field outside the conductor. Hence, there is a time-varying electric field in the vicinity of the wire.

  Is there an error in this question or solution?
