The electrode connected with negative terminal of battery is called
Correct answer: B. Cathode
- A. Electrode
- B. Cathode
- C. Anode
- D. Electrolyte
Explanation
The electrode connected to the negative terminal of a battery or an electrochemical cell is called the cathode. At the cathode, reduction occurs during the electrochemical reaction. Electrons from the external circuit combine with ions from the electrolyte, reducing them and completing the circuit. In a voltaic cell or battery, the cathode is where the reduction half-reaction takes place.

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.
