The electrode connected with positive terminal of battery is called
Correct answer: A. Anode
- A. Anode
- B. Cathode
- C. Electrode
- D. Electrolyte
Explanation
In electrochemical cells or batteries, the electrode connected to the positive terminal is called the anode. It is where oxidation (loss of electrons) occurs during the electrochemical reaction. Electrons flow from the anode through the external circuit to the cathode. This flow of electrons constitutes an electric current.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
