Electricity and Circuit Quiz: The Cell

What is a cell in an electric circuit?

• A unit of measurement for weight

• A type of battery used in watches

• A small room in a building where prisoners are kept

• Device that generates electrical energy through chemical reactions

What is the function of a cell in an electric circuit?

• To provide the energy needed to push the electric current through the circuit

• To absorb the electric current

• To block the flow of electricity

• To generate heat in the circuit

Name the two terminals of a cell.

• Positive terminal and negative terminal

• In terminal and out terminal

• Left terminal and right terminal

• Top terminal and bottom terminal

What is the difference between a primary cell and a secondary cell?

• Primary cells and secondary cells both have a fixed chemical composition, but primary cells are rechargeable and secondary cells are non-rechargeable.

• Primary cells and secondary cells have the same chemical composition, but primary cells are rechargeable and secondary cells are non-rechargeable.

• Primary cells are rechargeable and have a fixed chemical composition, while secondary cells are non-rechargeable and can be reused multiple times.

• Primary cells are non-rechargeable and have a fixed chemical composition, while secondary cells are rechargeable and can be reused multiple times.

Explain the working principle of a dry cell.

• Friction between the electrodes creates electric current

• Sunlight absorbed by the cell generates electric current

• Chemical reaction between the electrolyte and the electrodes generates electric current

• Magnetic field around the cell produces electric current

What is the voltage of a typical AA battery cell?

• 2.5 volts

• 1 volt

• 3 volts

• 1.5 volts

How is the voltage of a cell related to its chemical composition?

• The voltage of a cell is related to its chemical composition through redox reactions.

• The voltage of a cell is related to its chemical composition through magnetic fields

• The voltage of a cell is related to its chemical composition through sound waves

• The voltage of a cell is related to its chemical composition through gravitational force

What are the common materials used in the construction of a cell?

• wood, paper, and fabric

• plastic, glass, and rubber

• iron, copper, and aluminum

• zinc, carbon, and manganese dioxide

Explain the concept of internal resistance in a cell.

• Internal resistance is the resistance outside the cell

• Internal resistance is the measure of the cell's voltage

• Internal resistance is the ability of the cell to store energy

• Internal resistance is the opposition to the flow of current within the cell itself.

How does the number of cells in a series or parallel connection affect the total voltage of the circuit?

• The number of cells has no effect on the total voltage

• The total voltage decreases in both series and parallel connections

• The total voltage of the circuit is affected differently in series and parallel connections.

• The total voltage increases in both series and parallel connections
