    Hi,
    Can someone verify if what I am saying here is correct.

    When you hook a battery to a conductor chemical reactions happen which results in a difference in charge between the terminals of the battery. This creates a net electric field from positive to negative. Electric potential is a way to quantify each position in the circuit/ electric field. The negative terminal is defined as 0v to avoid negative voltages and the energy to take a unit positive charge from the negative terminal to any point defines the electric potential for that point, and as its a unit charge the potential energy of that charge. The electric field exerts a force which causes charge to flow (accelerate the collide with something) as long as there is free charge in the conductor . the potential difference between two points is the loss of pe per unit charge when it moves between them.

    Thanks

    The negative terminal is often defined as 0V but it doesn't have to be... -ve voltages are acceptable.

    usually you'd draw an earth symbol


    on your circuit to show the point you want to define as zero potential
