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.
After the hydrogen fuel at the core has been consumed, the star evolves away from the main sequence on the HR diagram. The behavior of a star now depends on its mass, with stars below 0.23 M â becoming white dwarfs directly, whereas stars with up to ten solar masses pass through a red giant stage.ulsating stars in this part of the instability strip that intersects the upper part of the main sequence are called Delta Scuti variables. Main-sequence stars in this region experience only small changes in magnitude and so this variation is difficult to detect.
