No. Larger stars are generally brighter. Blue giants are the brightest stars while red dwarves are the faintest.

Why do the big stars shine brighter than the smaller stars?
The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
How can stars have different absolute brightness?
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
How size and brightness of stars are related?
They are related because the bigger the star the brighter u can see it otherwise the smaller the star the duller it is to see.
Which is brighter larger stars or smaller stars?
Brightness is related to distance. However, from the same distance, an O class star is much much brighter than a M class star. As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.
Is the sun brighter because it is closer than the other stars?
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.

When compared with most stars are planets brighter or smaller?
Well,planets do not have any light of their own so they are definitely not brighter and yes there may be some stars smaller than the planets but most of the stars are bigger than the planets . But on the whole the Space is not that much explored so that we can get any cumulative answer.
Which star is brighter one with a 6.3 magnitude or one with a magnitude of 1.4?
The smaller numbers indicate brighter stars. Also, a negative magnitude is even brighter than zero magnitude.
How can stars have different absolute brightness?
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
Why sun is a star?
The Sun is just like other stars - some are bigger, some are smaller, some are brighter or less bright - but the Sun is similar in size, composition and behavior to stars. The only difference is that it is so near that it looks much, much brighter.

How do stars use frequencies?
The electromagnetic radiation (including light) have frequencies. Stars may also pulsate (get larger and smaller, and thus brighter and less bright) at a certain frequency.
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
How do star are more brighter than other stars?
Stars are more brighter than other stars because they have different characteristics that affect their luminosity. Luminosity is the amount of energy that a star emits per unit of time. It depends on the star's size, temperature, and distance from the observer. Some of the factors that make stars more brighter than other stars are: Size: Larger stars have more surface area and can emit more light than smaller stars. Temperature: Hotter stars have higher energy and can emit more light than cooler stars. Distance: Closer stars appear brighter than farther stars because their light has less space to travel and lose intensity.

How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
