What else can I help you with?
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
Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
How much energy does a normal light-bulb make in comparison to a colored one?
Both normal and colored light bulbs typically have the same energy consumption in terms of electricity when producing light. The difference lies in the design of the colored bulb that filters out certain light wavelengths to produce colored light, which can make it appear dimmer compared to a normal bulb of the same wattage.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
What energy changes take place when a light switch is turned on?
mechanical to electrical to light energy
What do you need to know to calculate how much energy light bulb uses?
You should be able to read the power off the bulb or its packaging.
What is the formula to calculate how much a light bulb uses?
The formula to calculate the energy usage of a light bulb is Power (Watts) x Time (hours) = Energy Used (Watt-hours). For example, a 60-watt light bulb used for 5 hours would consume 300 Watt-hours of energy.
What is the time duration of a 9 volts battery using 5 volts bulb?
The light-bulb will probably burn out if you connect it directly. Other than that, you CAN'T calculate the time duration based on the data provided. The duration depends on how much energy the light-bulb uses, and how much energy the batter is able to store. Voltage is NOT a unit of energy.
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 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.
How much energy does it take to run a 15w fluorescent light bulb for 24hrs?
To calculate the energy used by running a 15W fluorescent light bulb for 24 hours, you can use the formula: Energy (kWh) = Power (kW) x Time (hours). In this case, the energy consumption would be 0.36 kWh (15W x 24 hours / 1000).
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.
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 does a 5 watt light bulb use off?
A lot
Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
