Light travels exclusively through space or along optical fibres by the mechanism of electromagnetic propagation. Electrical energy can also do that, in which case it is called microwave radiation or radio waves, but it can also be carried on wires.

∙ 14y agoThe relation between power and energy is simply that power is the rate of energy flow. This applies to any sort of energy, whether electrical, mechanical, or other, In electrical engineering, power is in units of Watts, or multiples of Watts, which represents the flow of electrical current times the potential difference in the circuit, thus power (Watts) = Volts x Amps. Note that 1 Watt = 1 Joule per second (this applies to any type of energy flow). Therefore electrical energy can be expressed in Joules, ie power (Watts) = energy (Joules) per second. However in electrical work we measure volts and amps normally, so this gives power in Watts directly. Energy is usually quoted as a multiple of power x time, so we talk of kilowatthours for example, this is a unit of energy, not power.

What are similarities and dissimilarities between a motor and an electric generator?
An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.
How do microphones and speakers work?
mechanical energy-electrical energy-mechanical energy
What is the difference between mechanical and electrical transducers?
The mechanical transducers are the mechanical elements that are used for converting one form of energy into other form that can be measured easily. Electrical transducers may be classified as active or passive. The active transducers generate electric current or voltage directly in response to stimulation
Difference between a generator and a motor?
A generator converts kinetic energy into electrical energy; a motor converts electrical energy into kinetic energy.
A generator changes mechanical energy to what?
Electrical Energy
What is the difference between a electric motor and a generator?
the difference between a electric motor and a generator.Motor- is a device or equipment which convert electrical energy to mechanical energy.Generator- is a device or equipment which convert mechanical energy to electrical energy.
What is the difference between DC motors and DC generator?
A generator turns mechanical (or other) energy into electricity. A motor does the exact opposite, turning electrical energy into mechanical energy (e.g. motion).
What are similarities and dissimilarities between a motor and an electric generator?
An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.
What is difference between generator and oscillator?
A generator is used to convert mechanical energy to electrical energy. An oscillator is used to convert dc to ac
What is difference Between energy and charge?
In my opinion charge relates to only electrical parameter while as energy can be electrical, mechanical ,chemical or otherwise. Viraj Gurjar virajgurjar@yahoo.com
The conversion of electrical energy in to mechanical energy?
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
An electric motor uses an electromagnet to change?
electrical to mechanical
What is the same between mechanical energy and electrical energy?
The same thing between mechanical energy, and electrical energy, is that both types of energies, have energy particles flowing through conducters, from the energy source, out to the place where the energy is likely needed.
What is the difference between a DC motor and a DC generator Why can't you use a DC motor as DC generator?
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
Which electrical device changes electrical energy into mechanical energy?
The motor changes electrical energy into mechanical (torque) energy.
What are the difference between dynamo and motor?
A dynamo takes in motion and outputs electricity and a motor takes in electricity and outputs motion. A dynamo converts mechanical energy to electric energy while a motor converts electrical energy to mechanical energy.
What types of energy does a tv use?
It uses electrical energy,mechanical energy.
