Term
 5.1.1 Define electric potential difference.
Definition
 The work done per unit charge to move a positive test charge between A and B.
Term
 5.1.3 Define the electronvolt.
Definition
 The energy that would be gained by an electron moving through a potential difference of 1 volt.
Term
 5.1.5 Define electric current.
Definition
 The rate of flow of electrical charge.
Term
 5.1.6 Define resistance.
Definition
 Resistance is a measure of how easily a charge can flow in a material.
Term
 5.1.8 State Ohmâ€™s law.
Definition
 Providing the physical conditions such as temperature are kept constant, the resistance is constant over a wide range of applied potential differences and therefore the potential differenceis directly proportional to the current.
Term
 5.1.9 Compare ohmic and non-ohmic behaviour.
Definition
 In non-ohmic behavior V and I are not proportional to each other. Examples of this include light bulb filaments and semi-conductor devises like diodes and transistors.
Term
 5.2.1 Define electromotive force (emf).
Definition
 Total energy difference per unit charge around a circuit.
Term
 5.2.4 Draw circuit diagrams.
