It depends on how much you use the light, and how much power costs in your area. You can find out the second by looking at your electric bill... it'll give the cost per kWh (kilowatt-hour). The difference between a 40 watt bulb and a 60 watt bulb is 20 watts, meaning you'd have to leave the light on for about two days straight for the savings to be even one kilowatt-hour, and if it were on all the time in a year you'd save 180 kWh or so... almost certainly less than $20.
for about 3 DOLLARS
Zero, nothing. It wasn't until 1880 that Edison patented the first commercially viable incandescent light bulb.
That would depend on the how many watts the light bulb you are talking about. Also, it would depend on how much your power company charges for electricity.
Because to much electricity is getting through to the light bulb.
10 cm! It's always 10! Hhahahahaha. yeah no.
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.
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.
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
Thomas Edison's light bulb was patented in 1879. The cost of the original light bulb produced by Edison was around $1, which was quite expensive at that time.
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.
The average lifetime of an incandescent bulb is around 2000 hours.
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
