Electrical energy is usually AC, because AC can be stepped up to higher voltages with a transformer for transmission over smaller wires, and then stepped back down to serviceble levels with another transformer.
The device which convert mechanical energy in to electrical energy is "Dynamo".
a device that changes mechanical energy into electrical energy
Conversion of electrical energy into mechanical energy
At the basic level by moving a conductor in a magnetic field. There are many different configurations of generating machines, including AC and DC generation, but that is the scientific principle behind all of them.
Electrical
An electrical generator, these can produce AC or DC electric current.
Faraday's law states that a changing magnetic field induces an electromotive force, leading to the generation of an electrical current. This principle forms the basis for electromagnetic induction, which is the fundamental concept behind the generation of electrical energy in devices such as generators and alternators.
Electrical
nowadays to every single type of energy. such ac magnetic energy, chemical energy, kinetic energy,etc
Yes, the sun is a source of electrical energy through the process of solar energy generation, where sunlight is converted into electricity using solar panels.
A battery converts chemical energy into electrical energy. Inside a battery, chemical reactions occur that generate electrons, resulting in an electrical potential difference between the battery terminals. This allows for the flow of electrons and the generation of electrical energy.
That probably refers to an AC current or an AC voltage. That means that the electrical current is not continuously flowing in one direction, but changes direction all the time - typically at a frequency of 50 or 60 cycles per second in the case of household current. Similar for the voltage.
