ELECTRICS.

There is energy in many forms and electric energy easier these forms used easily transfer from one place to another and so we find that many of the household tools that we use depend on the energy of these machines often convert energy to another form of energy.

The electric lamp turns it into a light and the electric heater and turns it to heat if it is reddened by the electric bell. This energy turns into a sound and the energy shift in these three cases is done using wires.The electricity can be emitted during gas if the gas pressure is very low. This makes the gases light with bright light, as in neon lights, electric signs or street lights with sodium lamps. When the electrical current passes through some fluids, new substances sometimes form in the solution or start from it.

 This chemical effect is used in the preparation of certain materials such as aluminum and copper from their materials. This process is called electrolysis. And the phone which is also one of the most important electrical tools used in the home and office depends on electricity. In 1876 Professor Alexander Bell sent his assistant the first telephone message saying, "Mr. Watson, please reach me, I want you." Although the telephone system has undergone many improvements, the principle of modern telephone work has remained largely unchanged.The conversion of sounds in a simple phone depends on electric currents on an electric magnet. This magnet consists of a coil of wire inside a heart of wrought iron.

This electromagnet is installed behind a very thin metal disc so that it almost touches it. When this vibration vibrates in the transmitter, the sound wave generates changes in the magnetic file and at the current intensity that applies to the wires that reach the microphone in the future. These current changes are speedily proportional to the sound changes and are proportional to their intensity. In the future, there is also an electric magnet and a metal sheet. By making changes in the intensity of the current and changing the magnetic coil the vibrations of the

oscillator restrain the oscillations in the transmitter and produce the same sounds emitted in the microphone. The microphone is a microphone similar to the receiver of a simple phone but uses a conical horn of cardboard. When the cone trumpet vibrates in the microscope, the electromagnet vibrates with a larger quantity of air. This means that a larger electric energy can be converted to sound and not needed. To bring the microscope closer.
