100 Watts is 100 Joule/second. If you want the answer in Joule, you can base your calculations on that.
On the other hand, the electrical company will charge you by the kWh. In this case, it is more convenient to calculate as follows: 100W = 0.1 kW, that is the same as 0.1 kWh/hour.
What else can I help you with?
Does a 100w lamp use more energy than two 60w lamps?
NO. Two 60W lamps will use 120W - which is more than 100W !!
What energy does the lamp have?
The lamp has electrical energy, which is converted to light energy when the lamp is turned on.
Plug a lamp into an electrical socket and you turn electrical energy into this form of energy?
-- None at all if the lamp is switched off.-- If the lamp is switched on, then electrical energy is turned into a little bit ofvisible light energy and a comparatively larger quantity of heat energy.
What is the energy transfer for a lamp you plug into the wall?
The energy transfer for a lamp plugged into the wall involves the electrical energy from the power source (wall outlet) being converted into light energy by the lamp's bulb. The electrical energy powers the lamp's circuit, which then produces light as a form of energy.
What energy transformations occur in a lamp?
Electrical energy is transformed into electromagnetic energy.
What type of energy is a lamp plugged in and turned on to light a dark room?
it starts with electrical thats the main one but there is more
How much electrical energy does a 100W lamp use in 1 second?
Watts measure power. Energy is measured in joules and is the product of power and time. 1 joule = 1 watt for 1 sec Energy used in the example = 100 x 1 = 100 joules
What energy is present in a lighted lamp?
The energy present in a lighted lamp is primarily electrical energy, which is converted into light and heat energy. The electrical energy is used to power the lamp's filament, which emits light and produces heat when it becomes incandescent.
What energy transformation's in a lamp?
Electrical energy is transformed into electromagnetic energy.
How does a heat lamp provide an example of energy transformation?
A heat lamp transforms electrical energy into heat and light energy. The electrical energy powers the lamp, which then converts it into heat and light, providing warmth and illumination in the surrounding area.
What energy transfers in a lamp?
In a lamp, electrical energy is transferred into light energy and thermal energy. When the lamp is turned on, the electrical energy from the power source is converted into light energy, which illuminates the surroundings. Additionally, a portion of the electrical energy is also converted into thermal energy, which is why lamps can feel warm to the touch after being on for a while.
What are two common energy conversions involving electrical energy?
Electrical energy to sound energy with an alarm clock Electrical energy to light energy with a lamp
