- 1Kirchhoff's first lawthe sum of the currents entering any junction is always equal to the sum of the currents leaving the junction
(charge is conserved) - 2Kirchhoff's second lawin any closed loop circuit, the sum of the e.m.f.'s is equal to the sum of the p.d.'s
(conservation of energy) - 3non-ohmic behaviourthe current is not directly proportional to the p.d. across the component
- 4E.M.F.the electrical energy _supplied_ per unit charge
- 5Potential differencethe electrical energy _delivered_ to a component per unit charge
- 6electronvolt1 electronvolt is the wnwrgy transferred to an electron when it is accelerated through a potential difference of 1 volt
- 7photona quantom of energy of electromagnetic radiation
- 8superpositionwhen two or more waves of the same type exist at the same place, the resultant wave will be found by adding the displacement of each wave
