Understanding Electric Cells

What are the main components of an electric cell?

• The main components of an electric cell are electrodes, electrolyte, and separator.

• Battery, conductor, insulator

• Magnet, resistor, capacitor

• Wire, fuse, switch

Name two types of electric cells.

• Thermal cell

• Fuel cell

• Solar cell

• Primary cell, Secondary cell

What is the role of the electrolyte in an electric cell?

• The electrolyte allows ion movement and maintains charge balance in an electric cell.

• The electrolyte generates electricity by itself.

• The electrolyte acts as a conductor of heat in the cell.

• The electrolyte prevents any movement of ions within the cell.

How does a primary cell differ from a secondary cell?

• A primary cell is non-rechargeable, while a secondary cell is rechargeable.

• A primary cell has a longer lifespan than a secondary cell.

• A primary cell can be recharged multiple times, while a secondary cell cannot.

• A primary cell is used in high-drain devices, while a secondary cell is used in low-drain devices.

What chemical reaction occurs in a simple electric cell?

• Combustion reaction occurs in a simple electric cell.

• Redox reaction (oxidation and reduction) occurs in a simple electric cell.

• Synthesis reaction occurs in a simple electric cell.

• Decomposition reaction occurs in a simple electric cell.

What is the function of the anode in an electric cell?

• The anode functions as the site of oxidation and electron release in an electric cell.

• The anode generates heat to power the cell.

• The anode is the site of reduction and electron absorption.

• The anode serves as a storage unit for electrical energy.

What does the cathode do in an electric cell?

• The cathode generates electricity without any electron transfer.

• The cathode loses electrons and is the site of oxidation.

• The cathode is the positive terminal of the cell.

• The cathode gains electrons and is the site of reduction in an electric cell.

Draw the symbol for a simple electric cell.

• | |\n| |

• | | |

• |---|

• [ ]

What is the purpose of a battery made of electric cells?

• To store and provide electrical energy.

• To provide a source of light for illumination.

• To generate heat for cooking.

• To convert electrical energy into mechanical energy.
