Basics of Electronics

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
