Voltage difference causes charge to flow from?

Voltage difference causes charge to flow from higher potential to that of a lower potential.

Explanation:

Voltage Difference:

It is work done per unit charge in moving a charge from one point to another point.

V = Voltage difference

W = Work done

Q = Charge

Then,

unit : Volt or Joule/Coulomb

Flow of charge :

A free positive charge move from a region of higher potential to that of lower potential whereas a free negative charge moves from lower potential region to a higher potential.

Thus, a voltage difference is required for the flow of charge.

Direction of conventional current is from positive terminal to negative terminal.

Direction of electron is from negative to positive.

soil creep

The mass movement or mass wasting is a natural process by which the soil particles, boulders and slopes moves down the hill or mountain.

Soil creep is the slow downhill progression of rock and soil. It is characterized by the slow deformation of the materials on the slope due to exertion of prolonged pressure and stress. It forms characteristic patterns such as wrinkles, terraces on the hill slides.
