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 table below shows typical values for stars along the main sequence. The values of luminosity (L), radius (R) and mass (M) are relative to the Sunâa dwarf star with a spectral classification of G2 V. The actual values for a star may vary by as much as 20â30% from the values listed below.or example, the luminosity of the early Sun was only about 70% of its current value. As a star ages this luminosity increase changes its position on the HR diagram. This effect results in a broadening of the main sequence band because stars are observed at random stages in their lifetime.
