Answer to Question 1

A step-up transformer refers to stepping up voltage but the current will be stepped down. Because the current is smaller, the wire size can be made smaller and still be within the ratings.

Answer to Question 2

The voltage or current can be higher if there is a reactive load, and this keeps the transformer in the safe operating region.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
