  • Dynamo:
    • A dynamo is an electrical generator that generates direct current using a commutator.
    • Dynamo converts mechanical energy into electrical energy.
    • Dynamos were the first electrical generators with the ability to deliver power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter.
    • Today, the simpler alternator dominates large-scale power generation, for efficiency, reliability, and cost reasons.
    • A dynamo has the disadvantages of a mechanical commutator.
    • Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via solid-state technology) is quite effective and usually economical in comparison to other devices.

  • An electrolytic cell is a cell in which electrolysis of an electrolyte is done i.e. electrical energy is used to produce chemical energy.
  • Whereas, Electrolysis is used to break chemical bonds via a catalyst in a solution.
  • This converts some electrical energy into potential chemical energy.
  • A device that converts electrical energy into mechanical energy is called an electrical motor.
  • The working principle of an electric motor depends on the magnetic and electric field interaction.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. The sense perception that the brain releases after the eye converts light to nerve impulses is known as
