What happens to the brightness of the lights when you decrease the number of light bulbs in a circuit?

The brightness of the lights may or may not change depending on the circuit in which they are wired.
In a series circuit, all the bulbs (called lamps) will experience the same current flow. The same amount of current will be flowing through each one, and each one will be dropping some amount of voltage. If we remove some of the lamps and reconnect the circuit, the lamps will glow brighter because there is less total resistance in the circuit. The remaining lamps will end up dropping more voltage, and will glow brighter.
In a parallel circuit, removing bulbs (or adding them) will not affect the operation of the other lamps in the circuit (providing the voltage source is adequate). We know that each of the lights in a household circuit is wired in parallel, and turning one or more on or off won't affect the operation (the brightness) of any other light that is on.

What do you notice about the brightness of the bulbs in the parallel curcuits as you add more bulbs to it?
Nothing if the current capacity of the circuit is not exceeded. The extra bulb will draw more current and if the limit is not reached all bulbs will continue at their rated brightness. If the current capacity is overrdrawn either the circuit breakeer will break and stop all lights or if the capacity is not fused all lights will dim.
What happens when you close a circuit?
If there's a lightbulb it lights up, but basically it lets energy flow through, which completes it.
What happens to a parallel circuit if one light fails?
A parellel circuit does not fail if one light dies. In a series circuit, it's broken if one light fails (like the old style Christmas lights). See link for example...
Are street lights on a series circuit or a parallel circuit?
Parallel. One light burning out does not stop all current flow to the other lights.
If the lights in a room are off the circuit is?
Open.
You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
What happens to the current in the other lights if one light burns out in a series circuit?
It depends what is the outcome of burning. If that light has created open circuit, circuit will break and there will not be any current. But if there is short circuit means overall resistance is decreased. Thus current will increase. Besides overall brightness will also increase. Thus, if in a series lesser the number of bulbs more will be brightness.
Would you use Series or parallel circuit for Christmas lights?
Yes you would use a serial circuit You would use parallel circuit lights for a Christmas tree because if you used series circuit lights, and one of the bulb blows, the rest of the bulbs will go out. But with parallel circuit lights, if one bulb blows the rest of the bulbs will remain their brightness.
Why did all your dashboard lights go out?
Either the brightness control switch is turned off or the circuit blew a fuse.
What happens in a series circuit if a light blows?
The circuit current is interrupted and all the lights will go out.
What do you notice about the brightness of the bulbs in the parallel curcuits as you add more bulbs to it?
Nothing if the current capacity of the circuit is not exceeded. The extra bulb will draw more current and if the limit is not reached all bulbs will continue at their rated brightness. If the current capacity is overrdrawn either the circuit breakeer will break and stop all lights or if the capacity is not fused all lights will dim.
Are lights onor off in an open circuit?
If the lights are the load of the circuit, then the lights will be off if the circuit is open.
1996 Cavalier Chevrolet no Hi beam light and no DRL lights?
Hi beam lights only the High brightness filament of the headlight.Lo beam lights only the Low brightness filament of the headlight.DRL lights only the High brightness filament of the headlight, but at reduced current.Do you see the pattern?
What is a difference in the brightness of two lights indicative of?
It is indicative of their relative brightness, measured in candelas (units of brightness, also called candle power).
What happens when you close a circuit?
If there's a lightbulb it lights up, but basically it lets energy flow through, which completes it.
What happens to lights in parallel if one goes out?
In a series circuit each light completes its part of the circuit and connects to the next light. So, if one light fails, the circuit is broken and the flow of current to all lights must stop.
In an closed circuit will the lights be on or off?
Lights are on in closed circuit. It means that is a current flowing when circuit is being closed.
