What uses more energy a 60 watt light bulb or 18 watt light bulb?

This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

What uses more electricity a lit light bulb or an empty socket of the same rating switched on?
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
Non-living thing that uses energy?
A light bulb uses energy. It uses electricity.
Does a high watt bulb give more energy than a low watt bulb?
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
Do fans in general use a lot of electricity?
energy is energy It does not matter what you are using the energy for, it matters how much energy you are using A 200 watt light bulb uses more energy than a 100 watt light bulb A 200 watt motor uses more energy than a 100 watt light bulb A 200 watt heater uses more energy than a 100 watt light bulb
Is potential energy what a light bulb uses?
NopeNo, potential energy would be, for instance, a spring that is compressed. It could cause motion if released. It is stored energy. The light bulb uses electrical energy, which it converts to light and heat energy. potential energy is like when you wind up a torch or a radio
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent

When energy runs through a light bulb what kind of energy does the light bulb produce?
A light bulb uses electrical energy, and produces light, as well as heat.
Does an incandescent bulb and a light stick use the same form of energy to create light?
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
How has the light bulb impacted the society in a negative way.?
Uses more energy and power.
How has the light bulb impact the society in a negative way?
Uses more energy and power.
What is the job of a light bulb?
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)

Does a high watt bulb give more energy than a low watt bulb?
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
What is the Electrical power for a lightbulb?
The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
What does an energy saving light bulb do?
It uses less energy to produce the same amount of illumination as a standard light bulb
Is a light bulb an energy source?
No.it uses energy sources (electrical energy to light up
