Question
Fill in the blank by choosing the correct option.
- Anode, Cathode, Positive, Negative
- Cathode, Positive, Negative, Anode
- Anode, Cathode, Negative ,Positive
- Cathode, Anode, Negative ,Positive
Hint:
A battery refers to an electrochemical device (consisting of one or more electrochemical cells) which can be charged with an electric current and discharged whenever required.
The correct answer is: Anode, Cathode, Positive, Negative
The part marked as A is the anode, B is the cathode, C is a positive terminal, and D is a negative terminal.
- The batteries or electrochemical devices possess two terminals that are positive and negative terminals.
- They contain electrodes namely anode (oxidation takes place) and cathode (reduction takes place) which supplies the electric current.
