How do we decrease the brightness of a bulb?
If the bulb is of the incandescent variety, then reducing the current in the circuit will do this.
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
How would you compare the brightness of the bulbs as you increase the number of bulbs?
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
What happens when the amplitude of a wave becomes smaller?
look it up on ple.platoweb.comC: The brightness of the bulb would decrease.
How do you alter the brightness of a bulb?
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
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
How can brightness decrease?
The Solar System
What are some information on light bulb?
brightness
What is the connection between the reading and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.
What will happen to the lamp if current decreases?
brightness will decrease
