What else can I help you with?
How much current will an electric bulb draw a 220v source if the bulb filament is 1200ohm?
The equation that you are looking for is I = E/R. Amps = Voltage/Resistance in ohms.
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The wattage rating of a lamp bulb is a measure of the power it consumes, not the duration it operates for. The rating tells you how much power the bulb will use when it is in operation, but it does not provide information about how long the bulb will last before needing to be replaced.
Does a 100 watt bulb raise your electric bill?
Any electrical device "raises your electric bill", but only when it is activated. (only when you turn on the switch) A 100 watt bulb, left on for 10 hours uses 1 KW-hr. A 10 watt bulb left on for 100 hours uses 1 KW-hr. It becomes relatively simple to understand that if the power company charges you a set price (for example $0.15/KW-Hr) the 10 watt bulb would raise your electric bill much more slowly than would the 100 watt bulb.
How much wind power to light a bulb?
You need a wind power generator to make the electric energy to hook your light to. Maybe charging a battery with the wind generator and running the light bulb off the battery will provide better service.
A 100-W light bulb is turned on it has an operating voltage of 120 V how much energy is used each second?
A lamp will only operate at its rated power when subject to its rated voltage. So, provided your lamp is operating at its rated voltage (120 V), it's power will be 100 W, which means its consuming energy at the rate of 100 J/s.At any other voltage, its operating power will change, and the rate at which it consumes energy will change too.
How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
How much energy does an 11watts bulb use per second?
An 11-watt bulb uses 11 joules of energy per second.
How much current will an electric bulb draw a 220v source if the bulb filament is 1200ohm?
The equation that you are looking for is I = E/R. Amps = Voltage/Resistance in ohms.
Is a watt a light bulb?
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
What is the power rating of lights?
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
How much time will it take to capture geothermal electric power?
one second
How much does it cost you to burn a 0 watt light bulb for 24 hours a cost of 0.085156 per kwh?
A 0 Watt bulb does not consume electric power so the cost is zero.
How much work does a 100-watt light-bulb do when it is lit for 30 second?
3000 joules(J)
Shouldn't a lamp always be able safely to accept up to a 40W compact fluorescent light bulb if it is rated to accept a 40W incandescent light bulb--barring any physical size contraints?
Yes, your assumption is correct. Lamp fixtures are rated on how well they dissipate the heat given off from an incandescent light bulb. As CFL lamps run much cooler there is no problem using them in the same rated fixture that is incandescent rated.
What is the difference between a 3157 bulb and a 4114 bulb?
The 4114 is an ultralong-life bulb with its major and minor filaments rated at 14v. The 3157 has its major filament rated at 12.8v and a much shorter lifespan. 4157 is in between the two bulbs for lifespan rating. All three bulbs produce the same amounts of light.
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The wattage rating of a lamp bulb is a measure of the power it consumes, not the duration it operates for. The rating tells you how much power the bulb will use when it is in operation, but it does not provide information about how long the bulb will last before needing to be replaced.
