What does the number on the top of a light bulb indicate?
The number on the top of a light bulb indicates the wattage of the bulb, which is a measure of the amount of power the bulb consumes. This can give you an idea of how bright the light will be and how much energy it will use.
What does the wattage of a bulb indicate?
The power rating of light bulbs tells how much electric energy in watts the bulb consumes when burning. As an aside, a rule of thumb for estimating how much you are paying to burn a light bulb for a year, the number of watts equals the number of dollars. So if you burn a 40 watt bulb for a year it costs about $40. If only at night cut that in half and say it costs $20. If you burn 5 of the bulbs all year it's $200
Which is brighter 10 watts or 25 watts bulb?
That depends on so much more then just the watt of the bulb, but if you have two identical bulbs where the only difference is the amount of watt, then logic dictates that 25watt is brighter then 10watt
What is wattage of a light bulb?
The wattage of a light bulb indicates how much power it consumes. It is a measure of the bulb's energy usage, with higher wattage bulbs typically producing more light.
What is the connection of the reading of a ammeter and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
The size of the light bulb (wattage) affects the amount of energy it consumes. A higher wattage bulb will use more energy than a lower wattage bulb with the same wire and battery. The wire and battery provide the electricity needed for the bulb to produce light.
What reason for bulb blowing in an electrical circuit?
Too much current for the rating of the bulb.
How much amperage do headlights draw?
Depends on the wattage of the bulb. Formula is Power (watts) = Voltage * Current (A). Therefore for a 55w bulb, in a 12V car, bulb draws 4.6Amps.
Why is 60 watts written on the bulb?
The 60 watts on the bulb indicates the power or energy consumption of the light bulb. It tells you how much electricity the bulb consumes to produce light, helping you to choose the right bulb for your lighting needs and to ensure you are using the appropriate wattage for your fixture to prevent damage.
Does the life of a light bulb depend on its wattage?
Yes, Of Course The lifetime depends on the wattage. The wattage is the amount of Power the light bulb uses, and the life time depends on the power. Thank you
How much resistance does a light bulb create if it has a current of 25 mA around it in a 9 V circuit?
how much resistance does a light bulb creat if iyt has a current of 25 mA around it in a 9 V circuit?
If you have brighter bulbs will the battery last longer or will it run down quickly?
That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
