Name the basic components of an electric cell.
Circuits
Positive and negative terminals
Electrodes (anode, cathode) and electrolyte
Wires and casing
What is the role of electrolyte in an electric cell?
Increases resistance in the cell
Reduces the voltage output
Causes overheating
it allows the flow of ions between electrodes
Explain the functions of anode and cathode in an electric cell.
The anode and cathode have the same function in an electric cell.
The anode accepts electrons through reduction, while the cathode releases electrons through oxidation.
The anode and cathode do not play a role in the flow of electrons.
The anode releases electrons through oxidation, while the cathode accepts electrons through reduction.
How do the components of an electric cell work together to generate electricity?
The components emit light to produce electricity
Chemical reactions between the electrolyte and electrodes create a potential difference that drives electron flow through an external circuit, generating electricity.
The components physically rotate to generate electricity
The components generate electricity by absorbing heat
