Electrodo

The video explains the role of electrodes in different applications. In electrolysis, electrodes are rods inserted into a solution and connected to a power source. In electric batteries, electrodes contact a chemical mixture inside the battery. In medical equipment, electrodes connect metal wires to the skin.

What is the primary function of electrodes in electrolysis?

• To measure temperature

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

• To store chemical energy

• To generate electricity

In a conventional electric battery, what do electrodes come into contact with?

• A chemical mixture

• The external environment

• A metal plate

• A magnetic field

How do electrodes function in medical equipment?

• They measure blood pressure

• They generate electrical signals

• They connect metal wires to the skin

• They store medical data

Which of the following is NOT a use of electrodes?

• Connecting to a power source in electrolysis

• Contacting a chemical mixture in batteries

• Connecting wires to the skin in medical devices

• Measuring air pressure

What common feature do electrodes share across different applications?

• They are used to connect to a power source

• They are used to measure temperature

• They are used to facilitate electrical connections

• They are always made of copper
