About Energy Transfers
  • Mechanically – By the action of a force.
  • Electrically – By an electrical current.
  • By radiation – By Light waves or Sound waves.
  • By heating – By conduction convection or radiation.

Which of the following energy conversion takes place in a torch?

When the torch is turned on the chemical energy stored in batteries is converted into electrical energy. The electrical energy which is propagated in the form of an electric current through the bulb of the torch is then transformed into light energy and the torch glows.

What is the energy conversion that takes place in a battery?

electrical energy
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another through an external circuit. The flow of electrons provides an electric current that can be used to do work.Feb 25 2016

Which energy is converted into electrical energy by a solar cell?

Photovoltaic energy

Photovoltaic energy is the conversion of sunlight into electricity. A photovoltaic cell commonly called a solar cell or PV is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a nonmechanical device usually made from silicon alloys.

What energy conversion takes place in a TV?

A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen causing them to glow. In this case electrical energy is converted into light.

What energy conversion takes place in a light bulb?

electrical energy

In the light bulb the flow of charge through the filament heats it up and causes it to glow. In this way the light bulb converts electrical energy to heat energy and light energy.

What is the energy conversion in respiration?

Summary. Through the process of cellular respiration the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration glucose and oxygen are converted into carbon dioxide and water and the energy is transferred to ATP.

What energy transformation is a bicycle?

Therefore when riding a bicycle the rider’s physical energy is converted to the bicycle’s heat energy and kinetic energy. During transformation the total energy remains conserved. Hence the various energy transformations that occur when you are riding a bicycle are muscular energy to kinetic and heat energy.

How is sun energy converted to electricity?

When light energy from the sun strikes a photovoltaic solar cell it energizes the cell and causes electrons to ‘come loose’ from atoms within the semiconductor wafer. Those loose electrons are set into motion by the electric field surrounding the wafer and this motion creates an electrical current.

Which energy is converted into electrical energy by generator?

mechanical energy

An electric generator is a device used to convert mechanical energy into electrical energy. The generator is based on the principle of “electromagnetic induction” discovered in 1831 by Michael Faraday a British scientist.
