The correct answer is chemical energy.
Key Points
- The dry cell is a type of electric battery which is used for portable electrical devices.
- Electricity is produced through the dry cells from electrochemical energy. Hence, Option 1 is correct.
- A common dry cell is a zinc-carbon cell.
- The electrolyte is immobilized as a paste by a dry cell, with just enough humidity in it to allow current to flow.
- Like a wet cell, a dry cell can work without spilling in any direction, because there is no free liquid in it.
- The versatility makes it ideal for mobile devices.
- The first wet-cell batteries, in comparison, were usually fragile glass containers featuring lead rods sticking from an open-top.
- Hence, they required careful handling to prevent spillage.
- The dry-cell battery development made a significant advance in battery safety and portability.
- Batteries render electricity from chemical energy.
- Batteries consist of one or more different parts, or cells, which contain an electrolyte called a chemical.
- Every cell has two electrodes that are electrically conductive immersed in its electrolyte.
- The electrodes consist of different materials; one releases electrons into the electrolyte, and the other absorbs them.
- Once an electrical system is attached to the electrodes, an electrical current passes through it and supports its operation with electric power.
- The energy contained in the dry cell is therefore in the form of chemical energy.
Additional Information
- Thermal energy
- It is also called heat energy
- It is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.
- The energy that comes from the temperature of the heated substance is called thermal energy.
- Thermal energy is energy that comes from a substance whose molecules and atoms are vibrating faster due to a temperature rise.
- In physical sciences, mechanical energy
- It is the sum of potential energy and kinetic energy.
- It is the macroscopic energy associated with a system.
- The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.
- Nuclear power
- It is the use of nuclear reactions to produce electricity.
- Nuclear power can be obtained from nuclear fission, nuclear decay, and nuclear fusion reactions.
- Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
