When you use electrical energy, it powers electrical devices such as lights, appliances, and electronic devices by converting the energy into various forms of work. The electrical energy flows through a circuit, creating a flow of charged particles (usually electrons) that generate heat, light, or mechanical motion, depending on the device being powered.
Current flows along the wires to the bulb. There is a potential difference (voltage) between the wires and across the filament of the bulb, and as electric charges (current) flow down the potential gradient in the filament, energy is released from the electromagnetic field and converted into heat. The temperature of the filament rises until it is incandescent so that it emits light. Unfortunately it also releases about 80% of the power as heat.
The power drawn from the supply causes the generator at the nearest power plant (if steam-driven) to require more torque to drive it, and it slows momentarily, so that initially the energy for the bulb is supplied from the kinetic energy of the rotating parts. The phase angle of the shaft begins to lag slightly as a result, and sensors detect the small difference and request more steam to supply the turbine. More steam flows in from the boiler to correct the change, and this in turn causes more fuel to be supplied to the boiler to restore the status quo.
Thus any power drawn from the supply causes more fuel to be burned and more CO2 to be exhausted into the atmosphere.
A power plant using hydroelectric power, for example, uses a higher water-flow to achieve a higher output power.

What are three objects that use electrical energy?
Light bulbs: Light bulbs use electrical energy to produce light. Television: Television sets use electrical energy to power the screen and speakers. Laptop computers: Laptops use electrical energy to operate the display, processor, and other components.
What type of energy do hair straighteners use?
Hair straighteners typically use electrical energy, which is converted into heat energy to style the hair by passing it through heated plates.
What types of energy does a hairdryer use?
The hairdryer usually use the electrical energy. When heated, the hairdryer will convert electrical energy to heat energy which can then be used for hair drying.
What happens to the electrical energy when it passes through a household device such as a blender or a toaster?
When electrical energy passes through a household device like a blender or a toaster, it is converted into other forms of energy. In the case of a toaster, electrical energy is converted to heat to toast bread. In a blender, electrical energy is converted to mechanical energy to blend food.
When you turn on a toaster what happens to electrical energy?
When you turn on a toaster, electrical energy is transferred from the power source to the heating elements inside the toaster. The electrical energy is converted into heat energy, which warms up the toaster and toasts the bread.
What happens to the chemical energy in the battery when you use a electric toothbrush?
The chemical energy is initially converted to electrical energy. This electrical energy works its way through a motor and is converted to mechanical energy.
What happens after chemical energy from a battery turns into electrical energy?
The electrical energy provides power. When the chemical energy is depleted, the battery will not longer generate electrical energy.
When you turn on the toaster on what happens to the electrical energy?
When you turn on a toaster, the electrical energy transforms into thermal energy to toast your bread. =]
When you turn a toaster on what happens to the electrical?
The electrical energy gets transformed into electromagnetic (light) energy and thermal (heat) energy.
What happens when electrical energy is added to water?
When electrical energy is added to water it creates electric shock.
What energy happens when you plug in a blender?
electrical energy becomes kinetic energy and sound energy
What energy do appliances such as toasters and irons use?
All home kitchen appliances use electrical energy.
Which best describes the energy conversion that happens when hydroelectric power plants are used to make electricity?
Kinetic energy to electrical energy
What types of energy does a tv use?
It uses electrical energy,mechanical energy.
What kind of energy does a cell phone charger use?
potential electrical energy
What type of energy transformation do batteries use?
Electrical to chemical and chemical to electrical energy.
What are three objects that use electrical energy?
Light bulbs: Light bulbs use electrical energy to produce light. Television: Television sets use electrical energy to power the screen and speakers. Laptop computers: Laptops use electrical energy to operate the display, processor, and other components.
