Question

The process of lead action in a simple voltaic cell​

Answer 1

Answer:

The process of lead action in a simple voltaic cell is a chemical action that occurs while the current is flowing and causes hydrogen bubbles to form on the surface of anode. The action is called polarization.

Some hydrogen bubbles rise to the surface of the electrolyte and escape into the air and some remain on the surface of the anode. If enough bubbles remain around the anode, the bubbles form a barrier that increases internal resistance.

When the internal resistance of the cell increases, the output current is decreased and the voltage of the cell also decreases.

Hence it decreases the efficiency of the cell.

Answer 2

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. Wikipedia
