For some reason electric smokers don't convert the wood to charcoal and produce as much NO2 as propane. NO2 is what causes the rings. If it tastes good don't worry about it!
The smoke rings is caused by nitric acid building up in the surface of meat, absorbed from the surface. This nitric acid is formed when nitrogen dioxide from wood combustion in smoke mixes with water in the meat. Basically it is a chemical reaction between the smoke and the meat.
Some people cheat, coating meat with Morton's Tender Quick, will load up the surface of the meat with nitrogen dioxide and give you a great smoke ring. Because of the prevalence of this kind of cheating, smoke rings are no longer taken into consideration in barbecue competitions.
