Why is that when an electric bulb stay just as its bright when connected to a parallel circuit?

To operate at its rated power, a lamp must be subject to its rated voltage (the supply voltage). As each branch of a parallel circuit is subject to the same voltage (the supply voltage), each lamp will operate at its rated power.

Is series or parallel circuit cheaper?
A parallel circuit is cheaper because it is simpler but it does carry less power than a circuit so your light will be less bright.

What occurs to voltage in a series and parallel circuit?
In a DC parallel circuit, equal voltage is applied to each device that is connected in parallel. For example, if three devices are connected in parallel to a 9 volt battery, each device will have 9 volts applied to it. In a DC series circuit, the sum of the voltage drops across each device connected in series equals the source voltage. So say you have three devices connected in series, and they are connected across a 9 volt battery. Each device will have less than 9 volts across it, but if you add the voltage drops across each device togther, it will equal 9 volts. Batteries in series have an additive effect to the voltage. A single AA battery has 1.5V. Two in series will have 3.0V. Batteries in parallel do not experience an additive effect to voltage. To answer this question briefly there is a big difference. The major difference is the resistance the circuit offers when the same components are wired in series or parallel. I do not know how much you want to know, but resistance of a component is measured in Ohms. An easy way to think of ohms is how much force or energy is required to move an object. The less ohms a circuit has the more it can do with the same amount of energy, which in some cases can be a bad thing. To move on, lets say you have two light bulbs, to give a cliche example, and both are 2 ohm load. Now if you wired these two light bulbs in series, connect positive of one bulb to negative of the other and then the others to a battery, the bulbs would be half as bright as one bulb to the same battery. Yet if you wired these in parallel there brightness would be the same as if one light bulb was connected to the circuit. This is because the voltage in the parallel circuit doesn't decrease when you add a light bulb, whereas on the series circuit it does decrease. Hope that helps
Why are two bulbs in parallel bright when you build a parallel circuit with two bulbs a one d- cell battery?
Two bulbs in parallel are brighter than the same two bulbs in series, given the same potential voltage, because there is twice the available voltage to each bulb.
Explain which circuit you would use to light a bulb as bright as possible...a series or parallel circuit?
Think of it this way: If you want a lot of water to flow into one place, would you divide the river? However, it's irrelevant in this case, because the light bulb can only take a certain amount of current and voltage before it burns out. You can have amazingly bright for a millisecond or fairly bright for a long time. Your choice.
In a parallel circuit how is the brightness of the light bulbs?
the bulbs would be very bright seeing as the two or more light bulbs have very easy excusable paths for electricity to flow and get to the light bulbAnswerBecause the voltage across each branch of a parallel circuit is the same, each lamp will be subject to its rated voltage and, therefore, will operate at its rated power output.

Are bulbs in parallel brighter or bulbs in series brighter?
Lamps connected in parallel are subject to the same voltage. Provided this voltage corresponds to the lamps' rated voltage, then each lamp will operate at its rated power and at its full rated brightness.Individual lamps connected in series operate below their rated voltage (the sum of the voltage drops around a series circuit equals the supply voltage) and will, therefore, operate below their rated power and brightness. The lamps will vary in brightness; those with the lower power ratings will be brightest and those with the higher power ratings will be least bright.
How it is useful in your day today life comparison of intensity of bulb connected in series and parallel?
It's not really useful at all, unless you are an electrician or are studying electricity at school or college. After all, who cares how the lamp is connected -all most people are interested in, is whether the lamp is bright enough for its purpose.
When would a parallel circuit work better than a series circuit?
Efficiency isn't the question. They just do different things. For example, if you look at a typical lighting circuit in a house, all the bulbs on a circuit are in parallel. They each have the same voltage across the bulbs. If you rewired this so that the bulbs were in series then the voltage would be divided across each bulb and if one bulb burned out the others in series would get no current and would not light. If you had two 60Watt bulbs in parallel in your house, each would draw 1/2 Amp. Add another bulb and it would draw 1/2 amp as well, for a total of three 60W bulbs drawing 1.5 amps from the power source. If the same three bulbs were in series there would be 40 Volts across each one with a current of 1/6 amps per bulb. Hence each bulb would be about 1/3 as bright as in the parallel circuit.
