Question

A region of metal surface , act as anode which has : 1) relatively more moisture 2) dry surface 3) relatively low moisture 4) none . please give correct answer.​

Answer 1

The correct answer is 4.

Step-by-step explanation:

The anode is the electrode of an electrical device to which the carriers of a negative electric charge leaving the cathode move. In practical terms, for example when energizing an energy consuming device, the anode is connected to the positive terminal of the power supply and the cathode to the negative terminal; therefore, the anode is positive for the cathode.
