Electrode

The video explains the role of electrodes in different contexts: electrolysis, electric cells, and medical equipment. In electrolysis, electrodes are rods in a solution connected to a power source. In electric cells, they contact a chemical mixture. In medical devices, electrodes connect wires to the skin.

What is the primary function of electrodes in a circuit?

• To store energy

• To insulate the circuit

• To generate electricity

• To conduct electricity

In electrolysis, what is the role of electrodes?

• To change the color of the solution

• To measure the pH of the solution

• To insert into the solution and connect to a power source

• To act as a catalyst

How do electrodes function in a typical electric cell?

• They store chemical energy

• They generate light

• They make contact with a chemical mixture

• They insulate the cell

What is a common use of electrodes in medical equipment?

• To monitor heart rate

• To measure blood pressure

• To connect metallic wires to skin

• To administer medication

Which of the following is NOT a function of electrodes?

• Connecting to a power source

• Making contact with a chemical mixture

• Insulating electrical components

• Connecting wires to skin
