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.
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.
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 energy is consumed if device is rated at 1000 watts?
A device rated at 1000 watts consumes 1000 joules per second.
How much time is required for an operating 75 watt light bulb to dissipate 10 joules of energy?
1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds
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 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.
How much energy does an 11watts bulb use per second?
11 watts = 11 joules per second
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.
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.
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.
How much work does a 100-watt light-bulb do when it is lit for 30 second?
3000 joules(J)
How much charge flow through a light bulb in 4 second when the current is 35A?
14 c
