If a rheostat is connected in parallel with a light bulb, the setting of the rheostat
should have no effect on the performance of the light bulb, as long as the power
supply is able to maintain its output voltage and deliver the current demanded by
their parallel combination.

If the electrical conductivity in an electrical circuit decreases then the brightness of the light bulb does what?
Then the brightness of the light buld increases.
If you add an extra bulb to your series circuit what will happen to the brightness of your bulbs?
They will dim because you have more resistance in the circuit. More resistance means less current which means less light. The power is P=V*I = I/R*I = I²/R Think of blowing through one straw. Now attach a second straw end on with no leaks between joints and then attach a third straw in a long line. Which one is the easiest to blow?
What is the relationship between lamp brightness and resistance in a series circuit?
The higher the resistance the dimmer the light will become. The voltage drop (current) is proportional to the resistance as seen in the equation V=IR, since voltage remains the same throughout a series circuit if the equivalent resistance goes up the amount of current reaching the lightbulb must go down to equal the voltage thus creating a dimmer lightbulb.
Why will the current flow be different in a heated rear screen circuit than a side light circuit?
the heated rear screen circuit has a higher resistance compared to the side light circuit
What will happen if a second bulb is added to a parallel circuit?
-- The voltage doesn't change. -- If the second light bulb is identical to the first, then the total resistance drops by half. -- If they're not identical, then we have to know the details of both before we can calculate their combined effective resistance.
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
Light bulb in parallel circuit brightness?
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
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.
If the electrical conductivity in an electrical circuit decreases then the brightness of the light bulb does what?
Then the brightness of the light buld increases.
Which circuit can decrease the fluorescent brightness to the minimum amount?
You need to purchase a Fluorescent dimmer switch, no circuit can dim the brightness of the light safely.
What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
If you add an extra bulb to your series circuit what will happen to the brightness of your bulbs?
They will dim because you have more resistance in the circuit. More resistance means less current which means less light. The power is P=V*I = I/R*I = I²/R Think of blowing through one straw. Now attach a second straw end on with no leaks between joints and then attach a third straw in a long line. Which one is the easiest to blow?
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
Ohm's law applies: Current = Voltage / Resistance As such if you double the resistance of the light bulb you end up with half as much current.
What is the relationship between lamp brightness and resistance in a series circuit?
The higher the resistance the dimmer the light will become. The voltage drop (current) is proportional to the resistance as seen in the equation V=IR, since voltage remains the same throughout a series circuit if the equivalent resistance goes up the amount of current reaching the lightbulb must go down to equal the voltage thus creating a dimmer lightbulb.
How are light bulbs measured?
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.
How does area of the circuit affect brightness of bulb?
if light is low it can cuase the bulb brightnees.
