Why does a light bulb light in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
What does the intensity of light bulb indicate?
It indicates that the light bulb must be high of voltage trough the current......
The primary reason a light bulb emits light is due to?
voltage
Describe how a meter would be connected in a circuit too measure the voltage at a light bulb?
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
How many 1.5 volt batteries does take to light up a big light bulb?
Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.
Why does a light bulb light in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
When a light bulb is rated for 3.2 V does that mean that is the maximum operating voltage OR the minimum operating voltage OR or the optimum operating voltage?
When a light bulb is rated for 3.2 V it means that it is the maximum operating voltage to be applied to the bulb.
WILL 103 VOLTS LIGHT A 60 WATT LIGHT BULB?
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
What kind of battery makes a bulb shine brighter?
Usually a higher voltage will make a light bulb shine brighter; but if the voltage is too high, this can also destroy the light bulb.
What does the intensity of light bulb indicate?
It indicates that the light bulb must be high of voltage trough the current......
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
What voltage would a low voltage light bulb generally have?
24 volts
The primary reason a light bulb emits light is due to?
voltage
WHAT IS THE LOWEST VOLTAGE NEED TO LIGHT A LIGHT BULB?
A light bulb is manufactured to operate on a specific voltage. The voltage can be a low as needed and the manufacturer will compute the size of the filament that is needed for a specific wattage. If you are referring to a threshold voltage then that is another question that needs to be asked.
Why is there zero current when a light bulb out?
there is no voltage and resistance
Why does the voltage drop as electricity flows through a light bulb?
Do you mean why is the voltage in a circuit lower after the light bulb than before it? If so, it's because the light bulb filament has electrical resistance. When an electrical current flows through a resistance, there is a voltage drop across the resistance (Ohm's law).More fundamentally, the light bulb is producing light, which is a form of energy. The voltage drop across the light bulb comes from the fact that electrical energy is being turned into light. If voltage didn't drop, you would be producing energy from nothing. Furthermore, if there were no voltage drop, your circuit would behave the same whether you had no light bulbs, one light bulb, or eighteen million light bulbs - something that clearly can't be the case.
What happens when you connect a single battery to a light bulb?
If the voltage is appropriate, the bulb will shine.
