What happens to the brightness of a bulb if the volts are increased?

∙ 11y ago
The electrical potential energy increases as the voltage is increased. It further excites the filament in the bulb more than a lessor voltage would. Using good old ohm's law (Voltage = Current x Resistance), a larger voltage applied to a bulb at the same resistance increases the current proportionally and larger currents has the effect to cause higher temps in conductors

What happens when a light bulb get more than 120 volts?
The filament will melt AND MAYBE THE LAMP WILL EXPLODE
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.
What will happen if this 4.5 v bulb is connected to a 1.5 v cell?
The bulb need the correct voltage to operate. Your bulb would light if it is a 1.5 volt light. So the voltage of the supply and the light must be matched. Too little voltage won't light the light, too much will light it too much and blow it up.
Does adding more wires affect the brightness of the bulb?
NO

What happens to the brightness of the bulb when the second bulb is put into a series circuit?
it should become dimmer
How do you increase the brightness of a blub in a simple circuit?
Brightness can increased by increasing current flowing through the bulb, but current can be increased only indirectly, by 1. Increasing the Voltage across the bulb 2. Reducing the Resistance of the bulb. Brightness is proportional to Heat energy used/produced, which is = I*I*R*T I= Current R=Resistance T= Time
What would happen to the brightness of the bulb if you added a second bulb in with the first?
The brightness of a bulb would not change if you added a second bulb in parallel with the first.Unless, of course, the increased current exceeded the power supply's capacity causing a reduction in voltage.
How are light bulbs efficiency increased?
The brightness of a standard bulb is directly proportional to the amount of voltage drop across the bulb itself. Thus, to increase the brightness :-Pass more current across the bulb by reducing the resistance of the circuitIncrease the voltage across the bulb, or the circuit. Change the supply.
Does battery size matter in a flashlight?
The size of that battery can increase weight, but the size can improve burn time and brightness. Bigger batteries generally supply more power. If the volts are increased this increases the capacity for a brighter bulb. If the amps are increased this increases the burn time of the flashlight.
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.
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 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
What happens when a 60 watt light bulb receives 123 volts?
It should work fine. It will draw slightly less current than if the voltage was 120 volts.
