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)


How much energy does a normal light-bulb make in comparison to a colored one?

They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.


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.


How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?

Can you use 110v chandler in 220v country by changing a 220v light bulb The chandler said max 100w light bulb so do you need to use a smaller watts of a 220v light bulb?

The light bulb should still have the same limit - 100 watts, because the limit is set practically by how much heat they produce. You need to make sure the wiring in the chandelier is correctly insulated for the higher voltage.

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?

Convert the watts to kilowatts, multiply by the time to get the energy (in kWh), then multiply by the rate.

What energy is wasted from a lamp?

that is dependant on the wattage of the bulb, the wattage 40W, 60W, 100W, is the rated power that a bulb will use. 1kW is equal to 1000W 1kWh is equal to 1000W per hour. kW stands for kilo watt I hope that helps

Why do you think a light bulb feels warm?

A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
