So we know that an accellerating charge will emit EM waves.
Consider putting a voltage through a circular wire. Electrons are traveling in the wire with constant speed but their velocity is changing constantly as it is changing direction due to the shape of the wire. Now does that mean the electron will emit EM waves?
Consider another scenario, we now have a charged metal sphere. Does it emit EM wave if we let it drop to the ground?
