Smog, or smoke fog, is a type of intense air pollution.The word "smog" was coined in the early 20th century, and is a contraction (portmanteau) of the words smoke and fog to refer to smoky fog due to its opacity, and odor. 7. The cross-magnetizing effect of armature reaction may cause trouble in d.c. machines subjected to large fluctuations in load. H. August 14, 2017 at 4:26 pm. Therefore, we can write it as Itotal = Ia + Ish. Difference between cumulative compound & differential compound wound motors. (7 Marks) You can compare the prices of your options by using the Black-Scholes formula. From independence in 1947 until 1991, successive The total flux generated in such case in always greater than the original flux. When the total flux generates then it produces a high emf, so this connection is called cumulative. Smog, or smoke fog, is a type of intense air pollution.The word "smog" was coined in the early 20th century, and is a contraction (portmanteau) of the words smoke and fog to refer to smoky fog due to its opacity, and odor.
