ProfessorIn bathrooms, GFCI protection is required for all receptacles to prevent the risk of electric shock near water sources. The wire size for GFCI-protected circuits is typically required to be 12-gauge copper wire to handle the higher current demands in bathrooms. This ensures safety and compliance with electrical codes.

Who has given the rules of embryonic development?
The rules of embryonic development were established by developmental biologists Lewis Wolpert and Peter Lawrence in the 1970s. They proposed a set of rules known as the "French flag model" that explain how cells in the developing embryo become specified into different tissues based on positional information. These rules laid the foundation for our understanding of how a single cell transforms into a complex, multicellular organism.
What did Friedvich Hund contribute to atomic theory?
Friedrich Hund was a German physicist known for his work on understanding atomic structure, particularly the arrangement of electrons within atoms. He developed the "Hund's rules," which describe how electrons fill orbitals in atoms and molecules. These rules helped to explain and predict the behavior of electrons in atoms, advancing our understanding of atomic theory.
How do you find exceptions to the general rules and patterns of the planets?
To find exceptions to the general rules and patterns of the planets, astronomers analyze data collected from observations and experiments. These exceptions could indicate new phenomena or processes that challenge our current understanding of planetary science. By studying outliers and anomalies, astronomers can refine existing theories and develop new concepts to explain these deviations.
What is the ampere specification of switches and sockets used in house wiring?
In North America the standard receptacles and switches are rated at 15 amps. A dryer receptacle is rated at 30 amps and a range receptacle is rated at 50 amps. New code rules are allowing 20 receptacles in some specific locations.
How does the work of Gregor Mendel explain the rules of Heredity?
It explains the simplest form of genetic inheritance involving traits controlled by single genes having only dominant and recessive alleles. It does not directly explain genetic inheritance involving more complex traits (e.g. multiple interacting genes, genes having many different alleles, gene suppression).
