The few words were like the effects of a galvanic battery on Harry. He even pretended never to have seen a galvanic battery or a theodolite. His father was probably the first person who deposited metals for any practical purpose by means of the galvanic battery. The question came upon me like a shock from a galvanic battery. Volta was the first to construct what is termed the galvanic battery.
Best Answer: Most of the stars in the H-R diagram are classified as Main Sequence Stars -- in fact 90% of the stars in the sky are Main Sequence stars. The factor that affects the luminosity of a star is the stars mass (i.e. the bigger the star, the brighter it is) Source(s): I watch Discovery Channel.
Classifying Stars-the Hertzsprung-Russell Diagram. There are a few hundred billion stars in our galaxy, the Milky Way and billions of galaxies in the Universe. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns.Astronomers do this with stars.his group is called the Main Sequence so stars found on it are main sequence stars. Our Sun is one such example. Others include Î± Cen, Altair, Sirius, Achernar and Barnard's Star. Stars in group B are mostly 6,000 K or cooler yet more luminous than main sequence stars of the same temperature.
