Georg Ohm started his research with electrochemical cell. Ohm determined that the current that flows through the wire is proportional to its cross sectional area and inversely proportional to its length. Using the results of his experiments Georg Ohm’s was able to define the fundamental relationships between the voltage, current, and resistance. Ohm’s main interest was electricity, but then it turned into the battery invented by Alessandro Volta.The Ohm’s law is a outcome of his research, which we use to figure out the amount of Ohms, volts, and resistance in a parallel or series circuit.
Electromagnetic induction (or sometimes just induction) is a process where a conductor placed in a changing magnetic field (or a conductor moving through a stationary magnetic field) causes the production of a voltage across the conductor. This process of electromagnetic induction, in turn, causes an electrical currentc - it is said to induce the current. There is a motor in a generator which carries out this electromagnetic induction,as we switch on the generator the magnetic field lines between that motor get cuts off by the rotating coil which cause change in flux and change in the rate of flow cause induced EMF,cue to EMF at different points of coil cause current to get flow and then generator will get on
How electromagnetism improves our lives
The compass gives us a sense of direction when lost.
Credit cards allow us to have an account of money and not having to worry about cash.
Security devices allow department stores to catch people who steal.
VHS tapes allows the audience to be entertained with movies and recordings
Television entertains the audience with movies,videos, and episodes
Speakers allow others to listen to music off the computer
People are able to sing and speak in front of big crowds of people
