Describe the high-volume pig and some of its benefits.
What will be an ideal response?
A high-volume pig is very wide down the top, especially at the shoulders, which means they have a great deal of room in the body cavity for internal organs. Animals with large internal organs appear to grow faster and remain healthier. In addition, high-volume pigs have large, loose bellies capable of holding large amounts of feed. Such animals are efficient in the intake of feed and in their conversion of feed to body weight_

Answer the following statement(s) true (T) or false (F)
1. Transformers are of the dry type or oil filled. 2. A major disadvantage of the autotransformer over the insulating type is its lighter weight and compact size. 3. When there are several different secondary windings supplying the secondary conductors, an overload could occur on one or more secondary conductors and go undetected by the primary overcurrent protection. 4.
