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.
The HR diagram was created by Ejnar Hertzsprung and Henry Norris Russell. They formed this chart in the early 1900's. They classified the stars by their temperature against their luminosity. The blue and the white stars are the hottest, and the red, orange, and yellow stars are the coolest. The stars are then classified by their size. Giants and Supergiants, Main Sequence, and dwarfs. Stars along the Main Sequence are the most common in size and temperature. The Sun, in which out Solar System rotates around, is found in the Main Sequence group of stars.
