How much electricity use a light bulb -100W- in moment when you TURN ON the light switch?
Less than 0.02 watt/hours. Running your 100w bulb for an hour uses 100 watt/hours. The inrush current during the cold resistance of the bulb lasts for only a millisecond before the bulb is hot. This is insignificant on your electric bill even if you sat and flicked the lightswitch for the whole month, and is a common misconception that someone who didn't know what they were talking about made up.
Does a 100w light bulb use more electricity than a refrigerator?
A 100 watt light bulb draws a little less than one amp. A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.
Compare and contrast a 60 watt and 100 watt light bulb?
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
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.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
How much energy will a 100w light bulb convert to light and heat if it is left burning for 1hour?
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules

How much does it cost to burn a 100W light bulb for 24 h if electric energy costs 0.080 per kilowatt-hour?
To calculate the cost of running a 100W light bulb for 24 hours, first convert the wattage to kilowatts (100W = 0.1 kW). Then calculate the energy consumed in kilowatt-hours (0.1 kW * 24 h = 2.4 kWh). Finally, multiply the energy consumed (2.4 kWh) by the cost per kilowatt-hour ($0.080) to find the total cost ($0.080 * 2.4 kWh = $0.192).

If 100 J goes into a light bulb how much energy comes out of the light bulb in total?
The amount of energy that comes out of a light bulb is typically less than the energy that goes in, due to energy losses in the form of heat and light. The efficiency of a light bulb is determined by its design and technology. The amount of useful energy output can vary depending on the type of light bulb used.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
How much energy does solar power hold?
the sun gives about 15000 kilo calories in one square foot. when it reaches earth it will have the power to glow a 100w bulb.

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.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
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 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.
