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 HertzsprungâRussell diagram, abbreviated HâR diagram or HRD, is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures. More simply, it plots each star on a graph measuring the star's brightness against its temperature. It does not map any locations of stars. The diagram was created circa 1910 by Ejnar Hertzsprung and Henry Norris Russell and represents a major step towards ...
