Do free electrons travel to region of higher potential or lower potential ?

What is water potential?

What is solute potential?

Define water potential and solute potential.

Define:Stopping potential

What is the unit of water potential?

Define Barrier potential

True or False. Work has to be done against the electric field to take a positive charge from a point of lower potential to a point of higher potential.

If 20J of work is to be done in moving a charge of 100C from A to B, which of the two point is at higher potential? What is the potential difference?

Derive an expression for potential energy.

Answer the following question: Two conductors A and B are mounted on insulated stands and connected by a conducting wire as shown in figure. What is the direction of current when the electric potential of A is (1) higher than that of B(2) lower than that of B?
